I'm running out of ideas here. I have the OEM 7 Pin trailer wiring kit. All hooked up correctly as far as I can tell. Brake lights and turn signals work but I have no running lights. This is verified by the test light. Checked the fuses under the hood, wiring on the frame looked OK, pulled the relays in the kick plate and swapped them and still nothing. I checked the wife's Xterra that has the same setup and hers works fine. I get a light on the tail lights, brakes, battery and turn signals.
It seems to me that I either have a blown fuse somewhere (all lights on the truck work) or the wire is broke, which seems odd since the brake lights work.
Anyone got any ideas here? Anyone ever have an issue like this with the factory hookup?
