Question:
Hi. I am needing to replace the plug for my trailer wiring but am having a hard time finding what I need. The connection has 4 pins with 5 wires. The wires go White, Brown looks yellowish now but I think its supposed to be brown, black and white, yellow, green. I can send pictures if it would help... Thanks!

Hey Matt, thanks for reaching out!
The correct replacement for your trailer wiring/connector is the Wesbar Wishbone Wiring Harness with 4-Pole Flat Trailer Connector # 002402. For wiring that uses 5 wires but only has 4 pins, 2 of those wires go to the same pin and it's normally for the running lights.
If you confirm what functions those wires have, you can use Butt Connectors # DW05744-5 to connect all of the wiring together.
Let me know what you end up finding out!
