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 light flash and alternate!
Ive been slowly going over my grounds as well as the harness in the back is new and each side is grounded. I have new boards and bulbs too. I also have new brake light switches and a relay for LEDs. Any help would be greatly appreciated !
