I bought a 2015 2500 Laramie with a Cummins. Using the trailer 7 pin plug the right turn signal and right brake light won't work. I checked power at the 7 pin and no power. I checked the fuse I believe it was 81 and it was good but no power to the fuse block where the mini fuse plugs in. Does anyone have a wiring diagram? Thanks
