The correct trailer wiring harness for you trailer is the 35 Ft 4-Way Trailer Wiring Harness part # A35W42B. This is a wishbone trailer wiring harness which means there will be yellow and brown wires on one side and then green and brown wires on the other side. The white wire you have is for the ground and you can just mount this to a bare metal spot on the trailer frame for each side. However, if you want you can run this wire up to the main trailer ground which sounds like this is how yours is ran. They do not make trailer wiring harnesses that have this ground wire for each side ran but you can use part # DW02359-1 and run this yourself.
