Compared to your typical unbranded trailer wiring harness, the Wesbar version uses thicker gauge wire, a Wishbone Style wire setup for easier installation, and is backed by a 1 year manufacturer's warranty.

Wesbar Lighting and Wiring products are known for their top of the line quality by Trailer Manufacturers across the globe, this wiring harness is no exception. Each wire is 35 ft long, except for the White Ground Wire and Blue Brake Wire, which are about 5 ft long each, and are designed to mount on the trailer tongue and reverse solenoid, closer to the tow vehicle end of the trailer. This 35 ft length is perfect for longer trailers, or those wanting to wire their trailer up all the way to a set of lights at the top of their Boat Trailer Guide Poles. T he Blue wire runs to your Reverse Lockout Solenoid when operating disc brakes. The Functions of these wires are as follows: White (Ground Wire), Green (Right Turn), Yellow (Left Turn), and the Brown Wires Operate the Left and Right Side Running Lights. The Colors are the same White, Green, Yellow, Brown, and Blue wires that all trailer harnesses use.

T his Harness uses color coded wires to send power to your trailer's lights and brake functions. We have a 5 Flat Adapter to your Tow Vehicles 7 Pin Round Plug available on our website which would fix that issue. The additional wire in this case is the blue wire, and this new connection is used to send power to your Trailer's Electric Backing Solenoid, which is a powered valve that allows you to reverse your trailer without activating its Hydraulic Disc Brakes.īecause of this additional wire, you may require a new adapter to fit your trailer plug into your tow vehicle. T his Product uses a Standard 5 Flat Trailer Connector, which has an additional wire compared to the usual 4 Pin Connectors seen on most utility trailers. You may also be seeking out this product if you are adding Surge Disc Brakes to your Marine Trailer, or switching from Drum Brakes to a newer Disc System. This 35 ft Boat Trailer Wiring harness by Wesbar will replace your old or worn out trailer wiring with new, high quality 16 gauge wires.
