Where is the no idle temperature sensor?

So I work for the Big Blue Screw. They are taking out my broken ClimaCab and making it idle only over 75 or under 25. They are putting in a sensor to detect the exterior temperature. I am of the mind if I put a match to it, or a hair dryer, or lighter and make it think its 200 degrees when I want to idle the truck it should idle. So my question is where is the temperature sensor for the no idle override? The truck is a 2010 Peterbilt 387.....

 

Well yeah I have a Cummings, but I am sure Werner has this thing Password protected no? I am not sure I want to mess with it on that level. How would I reprogram it? But if I can find the thermostat and put a lighter to it so the truck thinks its >75 I can make the truck idle, no?

 

I figured it out. I talked to the mechanic installing the new sensor. The Ambient temperature sensor is located just passed the 5th wheel, on the driver's side and is zip tied to the wireing harness against the frame. The sensor itself has a copper terminal end. So my plan is to heat up the copper piece with a lighter or match, and maybe put something permanent there with a switch that will keep the area >75 degrees. As long as the truck thinks it is >75 degrees it will idle. Easy, Breezy, Beautiful, Covergirl!
