Expert Reply:
Trailer wire color varies depending on the trailer. ALWAYS go by function and not by color. Regardless of what kind of connection # PK12703 you're using. I would look at your trailer's manual or you can just test the function. I've included a diagram to help you with the testing and setup of your trailer.
