1983 Chevrolet Silverado Repair Question
Chevrolet Silverado Wiring Problem
Your tail lamps get voltage from the headlamp switch. I believe it is a brown wire that carries voltage to the tail lamps from headlamp switch. My old wiring diagram isn't that easy to read, as far as wiring color.
If you unplug the headlamp switch, just for testing, does the problem go away?
