Anyone have any suggestions for switch location where I wouldn't have to remove the dash?

I got some questions... What kind of switches would one person need? Just something with 2 prongs on the back? To computer and one to ground? And even with them both hooked in and both activated it will bump it up to 1600 or is there anything else you need to do? Also.. What does it mean 1600 RPM- short B7 and B8 together short?? If you get what im trying to ask.. hehe thank you!!

Just a simple switch, something that breaks contact with your chosen ground point. I used a heavy duty switch with dust boot for the toggle at Princess Auto.

And yes, 2 prong, one to PCM one to ground.

If your lights don't come on, and you have a short somewhere it means the power is grounding out before it gets to it's intended destination.

Shorting B8 and B7 means both pins are allowed to ground out (both switchs on)

Short = Short Circuit

Basically, with the OBDII system, you ground out the pins for the high idle, only pin B7 is grounded (Switch on) to get a high idle of 1070 (IIRC) ground pin B8 and you get 13somethin (Can't think of it now, lot on my mind) and ground both pins (both switches on) for 1600.

OBDI you apply power to A7 I think, and it only has one setting around 1000 RPM.

That's all.

Yea, there's some morning the polar bears even stay inside around here, but I still gotta work, helps a lot with gettin the engine to fire on all cylinders quicker, and also, added warmpth.

Switch Location

i poped out the cargo light switch and drilled a 1/2 hole in the lower blank slot, mounted my switch in there.

Just finished my high idle. I used smaller switches in the same area, under the speedo on the left side. Using smaller switch left room for more switches that area. (TCC override?? etc)

Convenient ground point is the PCM ground, just above the PCM.

Its nice to leave the truck running with the A/C on and it be real cold.

The fast idle will also be usefull when I get the 110v inverter installed.
