Splice this wishbone-style harness into your trailer's wiring to power each of the side lights. Split brown wires make installation easy. 4-Way flat connector plugs into the 4-way flat on your tow vehicle.

Just installed on a friends 5x10 trailer. Was fairly easy to do. Soldered and sealed connections with liquid tape. Should last a long time. I’m satisfied with the wiring
Product was as described and delivered timely.
Exactly what I needed to rewire a 20-year-old trailer that was starting to show it's age with inconsistent lighting performance and continuity issues. In addition to purchasing this lighting harness, I upgraded all my incandescent bulb side markers and taillights with LED units and complete rewired the trailer. etrailer had everything I needed in one place with excellent pricing and superb service. Everything is working great and I love the brightness and visibility of the LED lights.
I installed the 25 foot wishbone 4 way trailer harness on my restored 1969 boat trailer a year ago. It was easy to install. I tied the wires into two new side lights on each side of trailer and the tail lights. Everything worked and I would purchase again.
Low quality wiring. You get what you pay for. Insulation does come off when separating wires. If you need separate runs, buy the wiring on separate spools. If just using this for a trailer that does not require splitting the wires up, you should be fine, but I don't anticipate the wiring lasting longer than a few years.
This is a great harness if your rewiring your boat trailer. Plenty long enough for a 14-16ft trailer. Fast shipping and couldn't be happier with trailer products.
Got the wiring harness to make an extension to pull our trailer behind our camper with bikes and kayaks in. This worked great! I love etrailer!
Quality product. Just what I needed to finish up my trailer project. Will order from etrailer again.
I have completed wiring and all new lighting on my 1996 boat trailer, using etrailer! Their representatives are extremely knowledgeable about their products, with professional courtesy always!
Rewired my trailer and this harness was just the ticket. Shipped fast, great condition.
Haven’t installed the kit yet but I don’t expect any issues. As always, though, I’m very happy with etrailer.com. Great pricing and delivery as usual.
Great product, Shipping was excellent, will definitely tell my friends if they are going to re wire their trailer order from E-Trailer

Got this item to re-wire an old 18 foot utility trailer. Worked out just right. Very good value for the price.
