Replacement 4-Way Recommendation for Trailer with 7-Wires

Updated 07/17/2023 | Published 07/16/2023

Question:

I have a wiring harness on my boat trailer that has a 4 pole flat connector but it has 7 wires coming from it. I need a new connector or pig tail for a replacement t. My dog chewed the flat connector along with the wires and I need to replace it. Do you have one of these?

Sounds like your 4-way is a wishbone setup where the circuits that run to both sides of the trailer that are the same have two wires instead of just one. This is probably the ground and the running lights but it's hard to say for sure. Basically you would need to look at how the wires run to the back of the 4-way to determine which circuits are doubled for each pin.

We have the replacement 4-way part # 002402 which has just the running light circuit wishboned which would work great. For the other circuits that have two wires you'd just need to run them to the single wire of the 4-way circuit. It's possible you have three running light circuit wires and two grounds. That would be my best guess.
