2008 Ford F150. All my running lights on boat trailer work. When I put the truck in reverse I have no backup trailer/boat light which will not release my trailer breaks. It worked on my Skeeter but not on my Phoenix Trailer. I'm not sure where to start on my truck harness or where to start. Any help would be great
