What or where are the tail lights grounded? Im having issues with them, I have power to them, lights, brakes, signals, licence plate lights etc but no actual light at the bulbs, all of a sudden. Bulbs are all ok. The plug where the wires for the tail lamps stem from has two black wires, one going to each lamp assembly, a green for right signal and orange for left signal (all of which have power) and two purple stripe wires for a ground. They are in tact and they head above the rear fuel tank and to the cab. Where in the cab do they ground? I spiced into them and ran a ground wire to a known good ground to see if the lights worked but they still didn't. Im stumped. Up front I have marker lights, signals, headlights, but nothing in the back. I have power all the way to the trailer 7 way plug even, but no lights.
