I'll keep it simple. Installed trailer wiring in 89 jimmy, and screwed right through the pigtail without knowing. I can't get the dash lights to come on. The parking lights won't go on. The headlights will go on fine. With the headlights on, it's just the headlights no tails/markers. Signals and brakes still work. Fuses under dash seem fine. So think it's a headlight switch problem? Thanks

False alarm, turned out to be a fuse after all. Long days/week.
