Helpful Expert Reply:

There is not a standard wire color to function chart on a trailer for anyone to abide by so it will be best to test for function with a circuit tester. In order to check this all you need to do is start the vehicle, plug the trailer connector in, and test each of the wires while the corresponding signal is activated. Unfortunately, it is not as easy as green is ground etc.

I have attached a help article for you as well.
