If you had seen our wiring harness, you'd see why we blamed it first. (did one of those; forget to plug it in and let it drag along the ground for a few counties.)
We had a voltage tester, and it showed there was power from the truck to the socket.
It's a 9-pin socket so we have to use an adapter.Kendall was blaming the adapter for the lack of voltage through it.
Then I turned all the lights off and there was still power coming from the truck.
This is why we're not electricians.
