So you are saying the truck receptacle for 7-pin is not powering these lights?
Does the truck itself have operating brake/turn signals? If so, it would likely be a bad connection in the harness to the 7-pin connector.
If truck stop lights not working, most likely a fuse under hood or dash. Your owners manual should give the exact fuse location.

Jerry , I don't think the trailer ,and truck wiring are related ,they are all separate . I think one could be working without the other , in other words the trailer lights could be out because of fuse ,connection ,bad wire etc ,and the truck would be working .
