Parts Needed for Installing 5-Way Harness on a Boat Trailer

Question:

Hello, My boat trailer breaks require additional wire and I need wiring harness with 5 pin connector. But this kit comes with 4 pin wiring harness. Do you offer similar wiring harness with 5 pin flat connector that adds additional usually blue wire for trailer breaks? It looks like 4 pin wiring harness included in this kit is designed to run along both sides of trailer port and starboard sides making wiring easier. And it looks like 5 pin wiring harness you offer A25W5B comes with just straight wires and runs on one side of trailer complicating wiring. Can you help me right wiring solution for this kit and my trailer breaks? Thank you.

The best solution is going to be the part # A25W5B that you referenced. I will get into more of that here in a second, but the part # TL16RK only looks like it comes with all needed connectors and wouldn't require any hardwiring.

What you would want to do is use the part # A25W5B to provide the wiring and connector for your trailer but then use a junction box like part # 38656 to make organizing the wiring and running each of the wires to each circuit easier. I attached an install video for this box for you to check out as well.

I also attached a help article with trailer wiring diagrams as well.
