Replacement Trailer Wiring Harness For a Boat Trailer Using a 5-Way Flat Connector

Question:

I have a boat trailer I need to replace the wires getting old. The problem I am seeing is I have a 5 plug end but I have ten wires coming to it. Can’t find this exact piece anywhere can you help. I do use a round adapter to connect to ram 1500 if that helps?

Currently the only wiring harnesses we have with a 5-way flat connector are like the 25 Ft 5-Way Trailer Wiring Harness # A25W5B and 40 FT Harness # A40W5B. These harnesses use 6 wires coming from the connector. It has a short 5' blue wire to run to the surge brake electric lockout, a short 30" ground wire to attach to the trailer frame, 2 brown wires for the running lights on either side of the trailer, a green wire for the passenger brake/turn signal and a yellow wire for the drivers brake/turn signal. You harness having the 10 wires is likely due to running ground wires to each individual circuit rather than using the trailers frame to carry the ground circuit.

If you prefer to not use your frame as a ground source you will need to run additional ground wires with the other wiring and have it all connect on the harness.
