Will 20 ft. Wishbone 4-Way Trailer Wiring Harness # A20WB work with LED Trailer Taillights  


Will this wiring work on a trailer that has LED lights installed on it to replace the original bulb type lights. I need to replace the existing wiring as its old and cracking and the lights dont work only part time. I pull the trailer with either a 2004 or 2016 GMC pickup.

Yes, the 20 ft. 4-Way plus Wiring part # A20WB that you referenced will work great with LED trailer lights. There's no reason that it wouldn't work. This is a wishbone wiring kit for the running light circuit which means that the running light circuit has a wire for each side of the trailer. That's why there are two brown wires.

I attached an install video for this kit for you to check out as well.
