Hey guys Im new to this forum and this is my first post. I have a 2011 F250 6.7. There is a wire harness at the rear of the truck that is related to the trailer harness some how. It has two dead end plugs snapped to the trailer hitch. I have been to 2 different dealers and talked to some technicians and nobody can tell me what it is for or what is does. Has anybody figured out what the harness is?? Is it possibly for a fifth wheel electrial set-up? Any help is greatly appreciated. I will work on a picture.
