I have a 1990 GMC K2500 350/Turbo400 trans 4x4 8' bed. Every time I hit my brake pedal when the headlights and tail lights are on, my drivers side tail lights go out and my backup light lights up. Also when the lights are on and I use my driver side turn signal the tail lights and the backup...
I’m swapping a 4l80e for an nv4500 but the harness to the 4l80e has been cut off. I’m trying to locate the correct pink wire and light green wire that used to go to the neutral safety switch for the reverse lights.
Can anyone tell me the specific pin out locations for the other ends of those...
