F450 Lighting
My neighbor drives a company 2007, Ford F450. He wired in a trailer hookup. Everything was fine for some time (months of use). Now he has lost all truck body lights and also trailer voltages. Today, we checked all the fuses that we could find under the hood. We have no wiring drawings. He ran a wire from the battery to the rear to have temporary rear lights. We think there is a major connection that we are missing since all lights behind the cab are out. Please help.
