Wishbone 4-Way for Trailer that Has 7 Wires Ran to 4-Way

Question:

I am rewiring my boat trailer, I am looking for a 4 pin flat wiring harness, the 4 pin is what plugs into the truck. What cant find is my 4 pin connector that plugs into my truck has seven wires 3 white, 2 brown, 1 yellow and 1 green. One of the white wires attaches to the trailer as a ground. I am thinking the other two white wires are also grounds because four l lights sit in rubber grommets and need a ground. Do you carry a harness like this? I will need one around 25 feet. Thanks

The best solution we have is the wishbone 4-way harness part # A10-4225VP which is 25 feet long. This has two wires ran to the running light circuit (brown) like you mentioned which you can run to either side of the trailer like what you have now but only has the single ground wire which you can run to the trailer frame as well as to the other wires you have and you'd be set.
