I have one listed. See http://67-72chevytrucks.com/vboard/s...d.php?t=585200

At the firewall the production intermediate tail light harness is unplugged and the camper harness is plugged into it. The unplugged intermediate harness is plugged into the camper harness. The white wire goes to ground and the the red wire goes to the junction block on the fender. The balance of the wiring goes thru inside the bed and plugs into the camper. I've included a copy the factory wiring diagram.
