i got the plug down out of hitch and removed the black flex from plug to the left side frame. the plug is molded 1 piece about 4' long. the harness is wired to plug at that point, 5 of the wires are the same color .the hot wire the comes from plug is black. the harness wire that they used is orange. so next step is check the harness along the frame to the front. the ford fuse box under hood has 2 fuses and are both hot.
