Trailer Backup Light Harness Question

[Socalramfan]

I had the truck back to the dealer for some warranty work today and had them check it out. Turns out, something is wrong with the wiring harness from the cab to the bumper that feeds the trailer plug so they are ordering a new one under warranty.

Good to hear you’ve got a direction as to what’s the issue.

As mentioned previously, Magnum makes a great product and I’d be surprised if something slipped by quality control
