I have a new LLY with the Elevated Idle control built into the DIC. I can turn it on but it does nothing b/c, from what I read in the manual, it has to be below a certain temp. Is there a way to turn on the high idle regardless of outside temp. like the older LB7's could for PTO use?





Thanks

If there is still a PTO option we might be able to rig up a high idle similar to the way we do LB7s. I know that they changed the ECM in the 04.5's so we would have to research this further.

Like your manual says, it's got to be below 32 degrees F and the engine temp below, IIRC, 165 in order for the high idle to engage.


As Max said there might be a way, but that's a computer programmer deal I think...http://www.dieselplace.com/forum/smileys/Ermm.gif


The other thing, I think GM dropped the PTO option on the late production LLY trucks and now it seems like I read somewhere that it's back?

I have a 03 LB7 with the dic. how do I get the high idle to work?

gearhead, do a search for high idle and you should find lots of information.


Here is some info from kennedy diesel: http://www.kennedydiesel.com/docs/HIGH%20IDLE%20INSTALL%20FINAL.htm

Only the LLY engines have it from the factory, and I would like to be able to use it at will but no one's figured out how to do that yet.

Thanks!

Why don't you tap into the outside temperature sensor, add a rheostat (or just a particular value of resistance) and a switch to make the truck think it's really cold outside and then let the computer do it's thing. Wouldn't work if the truck is hot, but would any other time. This is an initial thought. Someone else may think of something bettah. Then when you want high idle, throw the switch, when you want the real outside temp, turn it off.


Dennis

Sounds like a job for Diesel Tech!http://www.dieselplace.com/forum/smileys/Geek.gif

The only problem with that would be that you could not turn the high idle for winching, etc purchases (unless the motor is cold?)

DuckhunterInTN,


I hadn't thought of that. I thought you might have been just trying to use it to warm up the truck. I have to study the Helm's a little more and see if I can come up with something. I've got a big Honey-Do list though, so give me a little time. Might be hard to overcome the engine temp one, unless you just unplugged or switched the temp circuit sensor, too. A DPDT switch, one for the outside temp, one for the coolant temp may work.


Dennis

I think I figure out how to do it. The only problem is that it looks like the PCM uses different plugs then the LB7. There for we will need to find pins for F Micro 64 Sealed connector. http://www.dieselplace.com/forum/smileys/Geek.gif With any luck, they will be the same. But I doubt we will have any luck.http://www.dieselplace.com/forum/smileys/Disapprove.gif

Max Power,


Let me know what you need to know, and I'll dig it out of the Helm's.


Dennis

Max Power,

Dennis








I already know what i need to know. http://www.dieselplace.com/forum/smileys/Clown.gif The only thing I am unsure of is if the pins are the same as the pre 03 since the ecm is different. Other then that I am pretty sure it will work. Just need to get the pins to test it.

I've got the pin-outs on every plug in the truck, PM me or let me know what you need, I'll look it up or scan the page and you can look at it yourself if you want.


Dennis

I have all that too. I really don't need any more information other then what the actual pin itself looks like.


The ecm will most likely not have a wire and pin going to the terminal at the ecm for PTO. So we actually have to buy the little pin from GM crimp a wire too it and insert it in the empty hole. I guess you probably aren't familiar with the procedure in the LB7. Edited by: Max Power

Does the connector not have the pin part number on it? I thought usually they do...

I found the part # (I think). Should be 15356826.


I'll order a couple and see if I can make it work.Edited by: Max Power

I have some information on the micro 64 connector. The connector is either 15437820 or 15452126 or 15452125.


Micro64 connector:


http://www.dieselplace.com/forum/uploads/Micro_64.jpg


Per the drawing for the Part 15452126 the pins are


http://www.dieselplace.com/forum/uploads/F46_terminal_parts.jpg


I would assume that since the connectors are all the same, the terminals are the same. Looking at the terminal part callout, it does reference 280GT or equivalent, and the 280gt connection system is one of Delphi/Packard's standard. It is used in more places than just this. The 280 connection system DOES NOT MAKE SENSE here though. That style is a flat blade style, not the round pin that I believe is in the connector. Pulling the part number 15356828 seems to be right though. It looks like:


http://www.dieselplace.com/forum/uploads/44D_terminal_specifics.jpg





Bottom line: The terminal that I think you need is 15356826, 7, 8 (when I pulled the print for 15356826 I got a print for 15356828). Good luck finding the place to plug it in. If you need the ECM schematics I can share what I have. I think the Helms has the same that I am looking at though.


HTH!!


ON edit: updated pin part numbers...Edited by: nassdmax

MP beat me to it. I was busy typing and searching while he throws the damn number right out there...http://www.dieselplace.com/forum/smileys/Geek.gif

We'll go with the 826 since thats the same # i came up with. http://www.dieselplace.com/forum/smileys/Big Smile.gif Thanks for all your work. Looks like we are on the right track.





Thanks again.

Okay, I get it now. I misunderstood what you said earlier. Cool.


Dennis

Max Power,


I'm trying to figure out what you are going to do with the PTO to make the high idle work. I have a pretty good idea, as I was looking through the mighty Helms I noticed there is a 56-Way F Micro 64 (GRY) that has a bunch of PTO/Cruise stuff going through it, and read the description and looked at the PTO schematic. The connector part number is listed as: 15357148, so I went to Delphi and found this stuff (below) on it. Any chance you could shed some light on how you did it on LB7? (I thought you'd trick the ECM by tripping the 'PTO on Switch Signal' and the 'PTO Engage Signal' and then the cruise control would work to change engine speed).


Not trying to be a pain in the a$$, I just love learning about this stuff and trying to figure stuff out.


Thanks,
Dennis

Here are the instructions to do it on an LB7.


http://www.kennedydiesel.com/docs/HIGH%20IDLE%20INSTALL%20FINAL.htm


On an LB7 basically all you do is provide +12v to pin C1-71 then press set on the cruise control twice and it will go up to 1250rpm.


My thoughts are that if we were to provide 12v+ to pin 6 of connector C-3 (grey), we SHOULD get the same effect. My only concerns are that perhaps GM has disabled the PTO option in the ecm. So it might require 'turning on' with a Tech II.


But I am not that far along yet http://www.dieselplace.com/forum/smileys/Big Smile.gif I have pin here that I think will work. I just need to try it. I have to get my ambition level up a bit first. http://www.dieselplace.com/forum/smileys/Big Smile.gif Since I don't have any real need for a manual high idle, I am procrastinating a bit.

Oh, man I knew JK had that on his site, but brain farted and didn't look at it. I was pretty close on my guess, though. Another question. I looked up the pins you're talking about: C1-71 (LB7)="PTO Enable"; C3-6 (LLY)="PTO on Switch Signal (PTO)" I originally thought you would have to trip C3-17="PTO Engage Signal (PTO)" also, but looking again, it doesn't make sense to do that one.


In the PTO section, there is no differentiation between LB7 or LLY, it just says "The 6.6L diesel engine does not have a TAC system and the engine RPM is strictly controlled by the ECM and THe FICM." There is a chart, however, which lists various operating parameters like Max Engine Speed, Standby RPM, etc, and it specifically lists teh L18 and the LB7 but NOT the LLY. Seems to conflict a little since the schematic clearly indicates everything exists in the LLY application. Any way to just probe the C3-6 (LLY) with a 12V wire connected to a needle and then have someone hit the Cruise Control buttons?


Thanks for the info,
Dennis

It would be pretty hard due to it's position. I'll figure something out.

I'll take a look tomorrow and see how tough it might be, it's too late tonight to be fishing around with a flashlight outside. SWMBO will probably freak out if I am under there doing stuff while it is running though. Who knows, maybe I'll get my 2 year old to press buttons. He loves to 'drive' Daddy's truck.http://www.dieselplace.com/forum/smileys/Big Smile.gif

Come on Tony, kick it up a notch (ambition), you know you could use this. It could good be real handy thing!


Steve

Yeah, definitely would be hard to do a temp to just try it out. Guess I'll wait for you to try it out MP. I guess my ambition level is lower than yours! http://www.dieselplace.com/forum/smileys/Big Smile.gif

I have a 03 LB7 with the dic. how do I get the high idle to work?


As Max said, do a few searches since your truck will require the install of the optional PTO related electrical stuff in order to get a high idle.


Only the LLY engines have it from the factory, and I would like to be able to use it at will but no one's figured out how to do that yet.





Here is the information for the LLY fast Idle.

http://www.kennedydiesel.com/docs/Fast_Idle_Description_LLY_Duramax.htm (http://www.kennedydiesel.com/docs/Fast_Idle_Description_LLY_Duramax.htm) Sorry, I missed the "AT WILL" part!

I might try this a little later today.

There three different "higher than normal idle speed" options - referred to by GM as "Fast Idle", "Preset PTO", and "Variable PTO". The latter two options are sometimes referred to as "High Idle" though Kennedy uses the terms interchangeably. He describes implementing the "Fast Idle" option. The PTO options provide more control with the Variable PTO providing for bumping the RPM up and down via the Cruise Control. See UI (Upfitters Integration) Bulletins 53 &amp; 64 for details.


I haven't got around to it yet but I am going to need to implement the Variable PTO option in order to control the voltage output of an under-hood welder that I have just installed.


Has anybody implemented this on an lly? Is the PTO Accessary Kit (Part Number 12497678) necessary?


Thanks.

It should work. The PTO kit should not be necessary but you will most likely have to visit a tech II to get the variable option added in.

Here is something else that might be of interest to you.


http://www.vmac.ca/throttle/index.htm

Max Power:
I don't see any application for the LLY on the site. Have You had a chance to investigate the high idle on the LLY
I think it would be a great mod.

Not yet. I'll try to set some time aside for it on Tuesday.

I tried to do it today. The pins that I have will not work. I need to find the pins before I can go any further.


My dealer says that the part # I gave him is no good and that GM doesn't seem to list it.



Any help?Edited by: Max Power

Max Power
Have You come up with a method of actuating the high idle
at higher temps on the LLY?

I would also like to know!

Nothing yet. I can't find the pins...... http://www.dieselplace.com/forum/smileys/Angry.gif


Canadian GM dealerships don't seem to have as much access to parts as American GM dealers. Can someone see if they can get the pins?

MP,


Did you try any of the other numbers that were thrown around earlier or just the 826 terminal? Just wonderin'


Thanks,
DennisEdited by: baimpala

Tried all of them.

I found some more numbers on the Delphi site, don't know if they were all included earlier or not. I know some were,

Sorry,


Having a hard time getting the format to clean up. . . Anyway, there are a lot more numbers than I originally though would be available.


Dennis

Anyone figure out the high idle for the LLY when it is warm?


thanks George

I tried calling V-Mac about one of their throttle commanders, but I haven't caught them during office hours yet. I'll try in the next few days.

I am still trying to get the pins. I tried buying from delphi but there was an error on their site. I'll try again later.

I'm going to try one of these, its suppose to be here thursday.

I hope that works but I bet it works for the LB7 only....or have you heard otherwise??

I haven't heard, but for the price i'll try it and let you guys know.

I think that price is wrong. It will be interseting to see if you get it for that price.

I think that is the same price listed at the BD website. I thought it was a typo on BD side but if Jegs has the same price maybe not.

Well it must be pretty simple then. They are probably just sending you a switch hooked to a wire with an end on it to hook up to the ECM. http://dieselplace.com/forum/smileys/Ermm.gif Edited by: Max Power

It was a simple switch on my 6.5

Bd has a similar price so I guess it must be right. I would think that this might not work with the LLY.


I am waiting for a reply from delphi to see if I can purchse a few of these pins.

BD's site doesn't have a seperate listing for the LLY so i'm assuming its for all Dmax models. But, I just emailed their tech support and am waiting for an answer as to if this will work on a LLY or not. And the price Jeg's has listed is correct, because i've already completed the checkout process. I let you all know what I find out.

Well it must be pretty simple then. They are probably just sending you a switch hooked to a wire with an end on it to hook up to the ECM. http://dieselplace.com/forum/smileys/Ermm.gif

You got it! The darn thing finally arrived today. Man what a simple piece of crap they are selling. I could of bought all the parts at Radio Shack for a few dollars(except for ECM pin). Here is a picture of what they sent. I haven't pulled my ecm apart yet but i'm 99% sure the pin they gave is only good for the LB7. Did you find the right pin yet Max Power?
http://www.dieselplace.com/forum/uploads/Z64_MVC-002F.JPG

No I haven't found a source yet. Sorry. http://www.dieselplace.com/forum/smileys/Disapprove.gif

Please keep me informed if you find a source.

Any update on this Tony or John??

Had frost on the windows this morning any ideas?

I haven't really been looking for the pins. I start looking again and see if I can get anywhere.

I talked today with Yawan Smith (Kodiak Industries) and he is putting
together an rpm controller for me to be delivered next week. He just
completed his first for an LLY (but has fabbed many for other electronic
throttle vehicles) and he asserts that all is good.

The only connection to the OEM is a ground and a small plug into the
OBD2. There are two options, either a switch for a specific rpm and/or a
dial for variable. i'm getting both.

I'll post impressions after I get mine installed. I''ll post Yawan's phone
number after he's done fabbing mine. http://www.dieselplace.com/forum/smileys/smiley2.gif

freddyo,


What's he asking for price?, or do you know yet?


Thanks,
Dennis

Very interested as well.

The PTO option would sure be ideal if I could just find the damn pins! No need to go to the expense of a seperate control module IMO.


I heard my high idle for the fist time today. It was above freezing so I was surprised. I find it comes on soon enough for me. If I had the choice I wouldn't have been using high idle today. Not cold enough to justify it in my opinion.


I will keep an eye out for pins in the mean while.

Don't know if this will help - I found it on another forum.


Good information for 2004 DMax owners;

There is stock fast idle, apparently (however this does not work on my 2002). Here's what you do;

1. Turn on the key (don't start);
2. Depress the accelerator to the floor and hold it there;
3. Depress the brake pedal 3 times within 8 secondes;
4. Release the accelerator;
5. Start the engine.

When you start, the engine is supposed to idle at 1250rpm for warmup. It'll drop back down to 650rpm when you touch the brake, push the clutch, put it in gear, etc.... It'll jump back up if the engine has been idling for more than 30 seconds.

All the LLY's have that built in. It is also available through the DIC if you have it. They also want to me able to turn it on manually. That is what we are trying to accomplish.

Does the medium duty use a completely different ECM? Mine has an
optional switch for a programmable high idle. They also option a
variable one. I just had the dealership set mine for 1200. Doesn't
matter the temp, flip the switch and it is on. I am curious if the
"option" can be purchased as an "add on".

Should be the same. Do you have a part #?

Dennis -

We've been trading items, etc. so I'm not sure and I don't want to bother
him until I get the unit. I think that it is around $300 and the price
depends upon the configuration, i.e., the type and number of controls. Its
a little pricey but I need the rpm's for the amps and the rpm control to
control my welder output.

Regarding the PTO option for the 2500HD, there used to be an empty
connector behind the dash for the PTO switch. You could then buy the
switch and a short harness and with a little Tech II programming get the
idle control functionality. I don't think that the connector is in the 2004.
Does anybody know?

The connector behind the dash is not the issue. IT has to be wired to the ECM. The LB7 wasn't wire to the ECM. We wired it to the ECM to enable the PTO option. We should be able to do the same with the LLY if we can find the pin.

The option code is UF3. I don't know if there is a part number for ordering the kit after the fact.

Have you looked here?

Well my parts guy can not get the pins through GM as far as he can tell. I guess I'll have to find a way to get it out of delphi.

The difference between the Medium Duty and the 3500 and under is that the Med duty comes equiped with the wiring for the pto option installed. The pins are not necessary and that is why it works on the Med. duty trucks.

Does anybody have a contact at Edge? Don't they use these connectors on their boxes? They must get the pins from somewhere when their harness is built.

The part # for the Switch + Harness kit is 12497678. It also comes with
an illustrated set of install instructions.

The switch is supposed to be plugged into the harness to be found
behind the dash. A picture shows it replacing the blank beside the
passenger air bag de-activate (looks like my '04).

The supplied harness has a connector at one end which is supposed to
plug into the "customer supplied cconnector" (on the PTO?) with
instructions for the blunt ends to be connected as follows:
(The colors are of the harness wires. The harness is 36" long.)

Does this help?

(Please excuse the mess above. I haven't figured out yet how to format a
table in a post.)Edited by: freddyo

The 2500 and 3500 does not have the plug so no that won't work. Thanks anyways.

Max,


Just checking to see if you've had any update on this issue?


Thanks, Steve

ttt

I can't find them anywhere. I don't know where else to look. http://www.dieselplace.com/forum/smileys/smiley5.gif

Darn.....I 've been hoping this would be doable thing. http://www.dieselplace.com/forum/smileys/smiley19.gif

So what other options do we have?


I guess this means I may be buying a throttle commander from VMAC.


Ouch!

Well, if all the information is in this thread. If you guys want to help me locate pins feel free. All we need is one little $1 pin and I am 99% sure this will work. There has to be a way to get these pins somehow.

Let me know how I can help, I'm not quite sure what I'm actually looking for, since I've never done the high idle on an LB7 either.


I'll help out in any way I can!

If you go back to page 1, all the information you need is there on which pin we need.

I found the part # (I think). Should be "15356826"


I'll order a couple and see if I can make it work.





Max,


Is this the correct part that is needed (Highlighted in red)? If so, I will also try to find it.

Should be, yes.


If you find some get some for me please. http://www.dieselplace.com/forum/smileys/smiley9.gifEdited by: Max Power

Will do, definitely! Hope I can find them. http://www.dieselplace.com/forum/smileys/smiley20.gif

Can't remember if I posted this link or not. If you know the
dimensions of the pin you are looking for, they will have it. . .

Forgive me if I'm being a real neophyte here!

AHAH!!!


I think maybe I've found a source!


www.powerandsignal.com (http://www.powerandsignal.com)


I'll try to contact them, or maybe you should Max Power?


You obviously know way more about this than me.

Whats this Elevated Idle for not up to date on this?

To help it warm up faster is one of the reasons.

AHAH!!!

Yep that looks like the ticket! Now hopefully they will sell us small quanti****. Check into it and let me know. Great find!

Alrighty, I'll get on the horn in the morning.


Time for me to kick some butts and take some names.http://www.dieselplace.com/forum/smileys/smiley16.gif

GOOD NEWS!


I contacted Power and Signal, and after a little sweet-talking I convinced them to sell the pins to a private individual!


Minimum order was 200, so I hope this works! I've got 200 of the things coming, so once I get them, we'll have to figure out something for distribution.


Max Power, I need to get your address so you can test these out since you're the brains of the outfit.


Mods, could you possibly make this a sticky? Thank you.

Good job coyotekid. It would be great to get this mod in time for the cold weather!


I wish I could be of some help with this but I am not the most wiring-savvy.


Coyote, if you need any $$ help on them let me know...

Good job. http://www.dieselplace.com/forum/smileys/smiley2.gif


I'll try it out the same day I get the pins.

Guys, how do you see the high idle operating being activated? a simple switch?

Excellent Kelly!!! Keep in the loop for this and how we all can share the cost. Again Great job, hope they work! http://www.dieselplace.com/forum/smileys/smiley32.gif

Guys, how do you see the high idle operating being activated? a simple switch?





There are a couple ways you can do it. I would hook mine up to the brake switch so that all I have to do is press set on the cruise control and it would idle up. I would also hook mine to the remote start.

What is the connection between the brake switch and the set button on the cruise?


I realize that was the way the LB7 high idle worked but I thought that was just a feature they built in specifically for the high idle on the LB7's.

It's just so you don't need another switch to turn on before you press set.

Ok, it's been a week since coyote said he had the pins.


Did Max get them yet?


Any news to report?

It's been a weeks since he said he could get the pins, not since he said he had them. Edited by: Max Power

Yeah, sorry for the delay, but unfortunately I can't control UPS. I'm waiting for them to get to me, and as soon as I do, I'll get several shipped off to Max Power pronto!

MORE GOOD NEWS!


I just received the pins about 5 min. ago, so I'll get some sent off to Max Power in the morning.


Max Power, how is the best way to send these? PM with the info.

Hey guys i just got my manual hig idle put in. Its just like I
had in my 2003 LB7. The had to enable the pto option with
the tech II . They wired up the switch to a connector behind the
little storage hole in the dash to the right of the stereo. They
had to put a pin in the bottom connection to the ecm in position #6 and
run a new wire to one of the wiring harenesses. I'm wasn't paying
attention at this point-sorry. My truck was one of the early
lly's so maybe it was different. They said it was a similair way
to doing the LB7's. Being from a cold weather area I can't live
with out it. At 40 below my truck won't even keep the frost off
the window's if it is only idling at stock idle. They put in the
high idle at the GM dealership in rosetown, saskatchewan.
Hopefully this helps somebody out.

Alright, I got the pins shipped off to Max Power today. According to the postmaster, Max should get them in about 4 working days.


Assuming that these DO WORK, I'll be glad to start distributing them to everyone.


Since shipping will be my biggest cost, I'm going to ask $5.00 for the first pin and $2.00 for each additional one. (I'll obviously be covering the shipping.)


As far as payment method goes, I'm not quite sure how to work that yet, but I'm looking into Paypal, so we'll see... . I'll get something figured out by the time Max determines whether the pins will work or not. I hope we can make this all work!

Okay, put me on the list if they work. If not, then take me off
the list. I guess I'm bored again. . . . another project. . .
. http://www.dieselplace.com/forum/smileys/hihi.gif

Keep me on the list also, unless it doesn't work. http://www.dieselplace.com/forum/smileys/smiley2.gif

I already have a full LB7 harness setup. I just need the new style pin.


Please keep me on your list for pin distribution.


I'm fairly confident I could have this working so fast it would make my own head spin.Edited by: 338_

I'm in. Can someone explain how this system will hook up and work? I dont have much time to read all 6 pages. Thanks

I just read through from the beginning... If a wire is run from C3-6 to
one of the wires near the brake pedal (Which one is it? I know it has
been posted, but search seems to be busted), the high idle should work
when you press the set or resume button. If it does not, a visit would
need to be made to a friend with a Tech II, then it would work, correct?



Once it works (either after wire install or that and a Tech II visit),
when you press the brake, high idle will shut off. It will stay off
when you put the truck in drive. What happens when you put the truck
back in park? Will the high idle kick in again? If so, how do you
diable high idle if you don't want it (such as truck has warmed up)?



What's the deal with the variable idle? Do you get one or two presets
(like 1250 and 1700), and also an adjustable idle, or just adjustable?

Edited by: Cougar281

thanks for the update guys... Max - fill us in with the info on
above questions, install, etc, and all your findings as you get
going. thanks again, and please put me down for one

Put me in too. I'll even help with the cost of the pins even if it doesn't work out. There is always a cost to develop something new.

When you put it back in park you would have to press set again to get the high idle back.


I am assuming you will get 1250 if you press set and around 1650 if you press resume.


The wire on the brake switch is the second one from the firewall side. I can't remember wire color. It will test +12v when the truck is in park and ground when the truck is in any other gear and/or the brake pedal is pushed.


I am pretty certain this will work as planned except I think you will need to get your truck to the dealership to have the PTO option enabled at which point you most likely can also have your rpms speeds set.

Just a question...


So has the object of this venture changed from just getting the "high idle" option that is displayed in the DIC to enabling the PTO option?

PTO is essentially high idle. Using the PTO function is the same as high idle. This is also the same way we add high idle to the LB7's.

Update:



I decided to go into work tonight to catch up on things before Monday morning. Guess what was sitting on my desk waiting for me? http://www.dieselplace.com/forum/smileys/smiley4.gif Special thanks to coyotekid for taking it upon himself to hunt down these pins. Without him this wouldn't have happened. http://www.dieselplace.com/forum/smileys/smiley32.gif



On to what I found.


The LLY ECM plugs are a lot easier to work with then the LB7 plugs. For those of you who have done this on an LB7 you are going to find this a lot easier. http://www.dieselplace.com/forum/smileys/smiley4.gif


I will post a do it yourself shortly. Hopefully my pictures turned out good. The only problem I can see people having is crimping the pins.


Now on to what you have been waiting for. Yes it works! No tech 2 re-flash required on my truck. Set is 1250 rpm and resume is 1650ish. Operates exactly the same as the PTO option on the 03 and 04 LB7's.


http://www.dieselplace.com/forum/smileys/smiley4.gif

Good stuff . . . several months and seven pages later, on to another project. . .

Details on the install can be viewed here:

Expect it to take you about an hour. Take your time and do it right. If you damage anything it could be a PITA to repair.

Okay, Coyotekid, how do you want payment, and how much?



Thanks,

Dennis

Yeah I know....I was just thinking at first you were trying to simply trick the "elevated idle" into working, not to activate the PTO high idle option. Same result either way, actually better because we have two RPM's now.


Thanks for figuring this out....another project for the winter now...http://www.dieselplace.com/forum/smileys/smiley4.gif

I would like one, just tell me how much? http://www.dieselplace.com/forum/smileys/smiley1.gif


good job on getting this donehttp://www.dieselplace.com/forum/smileys/smiley32.gif


Thanks, George

Let me understand this the "part" is that little thing that goes on the end of the wire? That is all?

Yep.

ok put me in for one.

Great Job MAX!!http://www.dieselplace.com/forum/smileys/smiley4.gif


I too will need a pin when they are available.................





OD

They are available. Contact Coyotekid, there is info from him on the previous page.

Max,


If you put a switch in the cab instead of using the brake petal then would that switch actually turn the high idle on or would you still have to hit the cruise buttons?

You would still have to hit the set button twice.

cool thanks. That is what I figured.

Put me in for one of the pins. Let me know where to send the money.

Just to let everbody know how things work in my truck if you pu the
switch in the cab to enable the PTO option when you flip the switch to
the on position the truck will idle upto what ever rpm you want.
This rpm level can be set with the tech 2 when you enable the pto
option. When you engage the pto with the switch you can also push
the cruise to the pre-set rpm of 1250 for the set button and 1650 for
the the resume button. I have my high idle set for the switch at
950 rpm. Hope this helps explain everything for you guys trying
to make it work. However if you set the pto rpm below 1100 rpm
hyou will find the engine will surge alittle during idle.

Graham, these peoples trucks will not operate like that unless the dealer reprograms it.

MAX, the link is broken for me, I would like the directions. I have read all the pages and have seen 'how to's' along the way, but wanted your final version. Can you either repost or give me a better way to find it. I have the pins coming shortly from Coyotekid.
