I can help you figure out exactly how to determine how to connect your wires, but wire colors are not an indicator of function on trailer wiring (or any wiring) because there is no universal color code, though that would be great. What you need to do to determine the functions of your wiring is to use the test the wires by function using the very handy Cordless Circuit Tester # PTW2979; plug in your trailer connector, have a helper engage the wire functions and you will know which wires are for which function.

I was unable to find your order number to determine which trailer lights you purchased from us but they should have come with some sort of instructions do you know which wires are for which function and you need to match the functions on the trailer wiring to the functions on the lights that you purchased from us.
