Got an 85 chevy truck and cant locate the wire to hook to my harness for TCC,,What color is it and where is it please. I am a wiring dummy so please help.

 

What ecu and engine do you have. Steve

 

Its an 03 5.3.. I know which wire is the TCC on the computer end but i cant figure out the 85 chev truck wire to hook into, having a hard time figuring where its at near the brake pedal. I know its hot when brake is off and turns off when depressed but i havent a clue looking under the dash for it.

 

I don't know if this will help or not or for that matter if it's even what you are asking.
