Anyone know how easy/hard it would be to relocate the amb temp sensor (that shows temp on the rearview mirror)? With my winterfront on, the temp isn't accuarate, it reads high from the engine heat just circulating around under the hood. It doesn't bother me that the reading on the mirror is wrong, but it won't let the auto high idle stay engaged as it thinks it is warmer than it really is outside. So, any ideas on how/where to relocate the sensor to to get an accurate reading with the winterfront on?
Also, still trying to find someone to sell me engine ECM pins so that I can do the manual high idle mod.....

Click on tech tips for relocation information. Kennedy has lots of good information on his web page -- look around.

Start with the local dealers on the pins. I got lucky and found a parts guy at the dealership that was willing to dig until he found them. I might have the delco numbers if you need them. I don't think that they help though. I gave them a part number and they could not find it that way. The parts guy actually found them by looking in the pin boxes that the techs use for repairing wiring harnesses.

PM me if you want the p/n's that I have.

Thanks. i've alredy been to the dealer with the pin numbers, went to drawer 19 where they were supposed to be, and those part numbers weren't in that drawer or any of the others either. They pulled a couple of their deisel techs in and none of them said that thye could identify which one was right without an old one to look at. So, I'm trying to find someone who knows that they have the pins for the LLY and just go that route.
Thanks for the help though!

thanks for the link to Kennedy. I've been to their site before, but never noticed the tech tip button. Lots of good info there.

Good luck finding the pins. I spent 30 minutes digging through a parts bin looking for one and never did. Kennedy has them for his DSP switch. He might be able to point you in the right direction on where to get one. I got my pin as a kit, which was just the pin and some wire. Sorry I don't remember where I got it. Look under the DIY thread I'm pretty sure I got the info from there, but I did it like four years ago and I can't remember what I did last week if you know what I mean.

Found the thread. http://www.dieselplace.com/forum/showthread.php?t=17853&highlight=high+idle

I beleive the outside temp sensor that feeds the mirror is a different sensor than that which feeds the ECM.
The mirror feed is off sensor just behind the grill just left of centre close to the bumper. Can be moved so it peeks out under the top winter front.
The ECM feed is in the engine air intake. I think this is built into the MAF sensor. That's the one that controls the engine parameters such as fuel tables, and high idle. Use a OBDII monitor to check the intake air temp and it is usually different than the mirror temp. A few degrees at higher speeds to very much higher (150 degrees or more) at very slow speeds on a hot day, than the mirror reading.
High idle, not PTO mode, needs a hand full of paramters all set to yes, in order to work. Intake air below freezing, Coolant temp under 150 F (don't trust dash gauge), just to name a few. At zero F, with the winter front on, Full high cabin heater on, it will cycle if left running for a couple of hours.

I believe you are correct on your asumptions, hows Arizona??
