Bad light switch probably. Or melted/hacked up wires.

brand new wiring harness and new light switch is there a difference in the gmc and chevrolet light switches?

switches? do you mean headlight switch or door pin switch. dome light of course has 12v from the brake pedal at all times. add a ground and the light comes on. grounds come from the door pin switch or the headlight switch. sounds like the ground wire is being grounded all the time. try tracing the wires to see for cut insulation.also check the headlight switch/pin switch if they're in the open position, turn the headlight switch, try new pin switches, disconnect 1 at a time. could be a bad headlight switch or dimmer for the headlights.

do you have access to a multimeter (or do you know how to read one for that matter)?

If you do, I can probably help you troubleshoot....

Check your door pins and make sure they aren't stuck. Mine stick sometimes. You don't have the interior light on do you? Turn the head light knob down to turn the over head off.
