Recommendation for New Wiring Harness on Vintage Trailer with Two Marker Lights


I am looking for a new wiring harness for a vintage redo trailer. Has license plate and 2 rear markers.


Expert Reply:

If your vintage trailer isn't equipped with electric brakes and you only need to power those rear marker lights, then a 4-Way harness like the Optronics # A35W42B will work great. This is a wishbone style harness that features two wires for the running lights - one for the right side of the trailer and one for the left - which just makes wiring it up a lot easier.

The harness itself features 35 feet of wire that you can cut if needed. I've attached an install video that you might also find helpful.
