Running new trailer lights doesn’t have to be complicated. This Optronics 35 ft. wishbone 5-way harness keeps the left and right stop/turn wires separate all the way to the lights, so you don’t have to split or double-back wiring. It gives you a clean layout that’s easy to follow and helps keep signals working right down both sides of the trailer.
If your trailer needs a 5-flat plug—like when you’re adding a reverse or brake lockout circuit—this harness has it built right in. The molded 5-flat connector makes it simple to plug into a vehicle with a matching socket and get all five circuits, including the extra blue wire for that fifth function.
The harness includes a 30? ground wire and a dedicated 5 ft. blue wire lead, giving you solid connections for both ground and auxiliary or brake signal use. Having those lengths ready to go means fewer splices and cleaner wiring from the start.
Because it’s a universal splice-in, plug-and-lead setup, this harness can be used on most light-duty trailers. Whether you’re rewiring an older setup or building one from scratch, it gives you flexibility without extra adapters or converters.

Hi everybody, Andy here with etrailer.com. Let's take a real quick look at this Wishbone Five-Way trailer harness. Now this is a 35 foot long split Wishbone Five-Way trailer wiring harness with five conductors, and then this thirty inch long ground wire. And this harness also comes with a fifth five foot long blue wire that can be used for lights or breaks. Obviously, I have this all bundled up just to keep it manageable here on my table. This is basically how you're gonna receive it as well.
But you see that blue wire here, and then you see the white wire here for ground. And just as a side note, this harness will work as an exact replacement for the truck light number that you see there, 002285. Well, I think that's gonna wrap up our real quick look today. I do hope that our brief time together was helpful for you. Again, my name is Andy.
Thank you for joining me.

Great
Exactly what I needed. Well made!
looks good haven't installed it yet reasonable price.
Perfect length for a 24 foot trailer with rear crossover wires. Great option for first time doing a trailer.
Works as it should
Joy did an outstanding job identifying the wiring harness that I needed to rewire my boat trailer. She ensured that all my hardware was included and fast shipping. I won’t hesitate to use your company. Kudos to you guys for excellent customer service!
It would be helpful if you included a wiring diagram for the 5-way wishbone. I tried to find it on your website but only the 7-way shows. I have installed the harness but the rear turn lights still don’t light. So I guess the bulbs are burned out again. I replaced them before buying the new harness. I don’t get it.
