Trailer Wiring Issues

[Five_O_Nomad]

Has anyone encountered corrosion with the 7pin wires past the harness that attached to the outlet?

I tried to tap into it and it looks like my wires have a ton of corrosion so no power.

Sorry no, haven’t had that issue. Is it just the connector at the bumper that’s corroded? Or the wiring harness is damaged?

If it’s just the 4/7 pin plug at the bumper, I’m sure that can be replaced without too much hassle.

The bumper is a separate harness, so that should be easy as well. BUT, my bodyshop broke the body side plug to the bumper harness, and mine is held together with a ziptie now. Clean the bail handle before trying to rotate the disconnect. Yes, it is all cheap crap.
