Trailer connects when it rains
I have a 2018 F350. When it rains, the truck thinks the trailer is connecting and disconnecting. I know this is an obvious short somewhere in the wiring. I have replaced both 7 pin connectors, (Bed & Bumper). Now, I'm trying to replace the wire harness itself. Does anyone have the part number for the wire harness coming off the bumper, or do you think I should clip the bumper side and tape it off since I only use the bed connection for my 5th wheel?
