Wiring a trailer can get confusing fast, but this 35 ft. wishbone harness keeps things simple. The split design sends separate running-light wires down each side of the trailer, so you don’t have to cross wires or add extra splices. That saves time when routing lines to both tail lights and keeps your connections neat and easy to trace later.
When your trailer is longer than average, short harnesses can leave you stretching wire or adding extensions. This one gives you a full 35 ft. of cable, long enough to reach the back of most utility or boat trailers without strain. There’s plenty of slack for a clean run along the frame.
A bad ground is one of the most common causes of trailer-light problems. This harness includes a dedicated 30" ground wire so you can attach a solid connection right where you need it. That means steady power for your lights and fewer flickering-light headaches down the road.
The standard 4-flat connector on the vehicle end makes it easy to pair with most trailer wiring setups. Splice-in leads give you flexibility to connect running, turn, and brake lights exactly how you like. It’s a universal-fit setup that keeps installation simple and dependable without extra converters or adapters.
