Expert Reply:
I'm happy to assist. The 7-way plug on your trailer will have the correct pin locations even if the colors don't match. It is not uncommon for different color wires to be used. I've attached a photo with the wiring location and function so you can match those versus the function. I've also attached a video and article to assist.
You can also use the circuit tester # PTW2993 to test power functions.
