Which wire is for reverse light in trailer harness plug)

[CAMDENN]

Problem solved. The cheap little tap connector that was supplied by Morimoto was defective. The little strip of metal inside the connector on the ground side did not connect from wire to wire. Just a manufacturing defect. Swapped it out to a new tap connector and bingo. Go figure.

So for anyone who needs to know, the green and brown wire in your tail light is hot for reverse and the black with yellow tracer is ground.

Don’t you hate it when something gives you all kind of issues and it turns out the simplest and cheapest thing was the problem.
