Im trying to figure out where the grey wire from my temp sensor goes on my PCM. Originally I was not going to use it but decided to because I want to run my cooling fans off my PCM.

I know my Yellow wire goes to # 74 on the Blue PCM connector, but I can find the pin location for the grey.

Would this be it? "52 GRY 23 Generator Field Duty Cycle Signal"

My engine is an LQ4 6.0L from a 2002,2500 HD truck with Blue/Red PCM

Look for the Temp Sensor Ground..I dont have a truck PCM Diagram infront of me otherwise I would tell you.

Look at PCM Blue 80..see what that is.

I still can't find it. I used this pinout for my setup.
