I have a 2000 F250 7.3 powerstroke and want to use my trailer brakes again. I am not getting a hot wire to the brake controller. I replaced my old controller with a new Curt Venuturer. It works for lights, turn and brake lights only. I have looked at the fuse panel under the hood and have a good fuse on #28 for the tow package. I had a problem with fuse #4 and found it had blown. When I replace that fuse my parking lights stayed on continually and my other lights on trailer would not work. I need someone to help with determining why there is no power from fuse box to trailer brake controller. Does anyone know what the problem might be?????
