This is a 35 ft Wiring harness for replacing your old or worn out harness on your Boat Trailer. This is a standard 4 Flat Harness with a Ground Wire. This Harness uses the standard White, Green, Yellow, and Brown Wires to successfully connect to your side-marker and tail lights. 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 Running Lights.  We carry this 35 ft length of trailer wiring for longer trailers and for customers desiring to wire their trailer lights directly up their guide poles.  Each wire is 35 ft long, except for the ground wire, which is designed to mount on the trailer tongue.  This is a 'wishbone' style harness.  It sends (1) brown wire, and (1) yellow wire down the left side of your trailer frame, and (1) brown wire and (1) green wire down the right side of your trailer frame.  This wiring harness is most common on small to average sized boat trailers not operating disc brakes. We have the 5 Flat Version of this harness if you are needing it for Disc Brakes.

I hate wiring
My trailer lights are like everyone else's, and they need attention every year. I went with pole lights, so I needed a longer harness. This one fit the bill. It's good quality with wire to spare. I also ran a dedicated ground wire to each light all the way up the length of the trailer. No connections are in the water and no grounds to the trailer frame to corrode and kill the lights. Remember the old adage when your trailer lights go out, "check everything and then fix the bad ground". It's always the grounds.
