my bighorn is not equipped, but there is a unused wire harness with plug behind the panel where the switch would be located..I'm curious where the outlet goes in the bed, and if any wiring is hiding someplace that can be finished.
I do have that..I'm guessing the plug is near that location as well?Depending on where you found it, it could be the wiring for the bed light switch, located on drivers side near taillight.
Ahh that could be the missing puzzle pieceI thought the 120v outlet was with the rambox and there will be an inverter switch by the power pedals switch.
