Backup and Running Lights

I have a 99 F350 Crew, LB, V10. The truck has the Ford Trailer Tow Relay Harness (F81Z-14A346-A) and the Trailer Tow Harness (F81Z-13A576-B) installed on the truck. I just tried to connect my truck camper harness and I have no running lights and no back up lights. I disconnected the harness at the frame connection at the back and used a digital meter to check for voltage at the main harness. I am getting proper voltage from the 12v feed line, and the stop and turn signals are working fine. If any one has any ideas, I would greatly appreciate it.

The first thing I would check would be the ground on the trailer.
