Ground wire in the wiring harness was said to be the issue. Brake lights would b\not work if the headlights were on. I replaced both rear wiring harnesses to the stop, brake and tail lights. Everything was good. Online prices were $33.00 per harness.
I keep burning my fuse on my right stop light. I changed the trail plug recepticals and the wires for the one inside the bed but it didn't help. looking for any suggestions
