So the factory trailer harness is present at the hitch but has no juice? Stay out of the fuse panel. You'll only spread the legs and cause more problems. You should have a high current at the column for the ignition switch, or run a 10 gauge wire from the battery. Do not pay $30 bucks for a relay. You are getting hosed..http://www.amazon.com/Absolute-RLS125-1 ... hrow+relay I can get you a wiring diagram of the major stuff if you need it. Column, parking lights, brakes, etc... If it were me, I'd buy these and be done....http://www.amazon.com/Maxxtow-Towing-Pr ... 9076767148
