All my lights work on the truck,,,but the running lights will not work on the trailer connection,,,It is factory installed with a 6 flat pin connector and a side mounted flat connector,, Niether connector works on the running lights, I have checked owners manual and every fuse I can find is OK ?????Anyone else have this problem ?????

 

wat u need to do is trace the wires back they should be a connector to the lights but for the brake controller it will runn up to ur dash where the controller plugs in
