How Does Non-Wishbone Style Trailer Connector Wire to Trailer that Had Wishbone 4-Way


Hi I have a wishbone trailer for my boat that has a problem with my running lights, I was blowing the trailer fuse on my truck every time I hooked up so I replaced the fuse and hooked up to a neighbors problem so that let me know my problem was with the trailer wires. I decided to rewire the trailer and tried to wire it the same way it originally was. The new harness I purchased had 4 wires green, white, brown, yellow the old harness had 6 wires 3 white, brown, yellow, green so I added a brown and 2 white wires to match. After installing the wire into the trailer all the side markers and rear lights had a white wire to it along with the brown and directional green and yellow wire, plug it to my adapter and still no running lights although Im not blowing fuses. I Just bought another new harness with 1 white, 2 brown, 1 green, and 1 yellow to rewire it again but before I do I want to know if the new harness will need to add 2 additional white wires or will I just need to hook up just the brown wire to my lights to work?


Expert Reply:

You'll need to take off of the white wires on your trailer wiring and run it to the single white wire of the new 4-way as well as all of the brown wires to brown wire of the new 4-way. That would be the proper way to run wishbone style circuits of a trailer to a non-wishbone style connector.
