I have a 2013 F350 CC. I was adding wiring to provide power for a camper shell and noticed 2 unused connectors attached to the frame in the back next to the spare tire. There is 1 large connector that has all of the wiring for the rear lights, sensors, and I think the trailer wiring. Right in front of it are two connectors that are unused, 1 is a 2 conductor that is white/black and the 2nd one is a 6 pin connector.
They look like they could be another set of trailer wiring connectors but I am guessing. Does anyone know what thy might be?
