4-Way to 7-Way Vehicle End Trailer Wiring Connector Color Code

Question:

I cant find the instructions for this adapter and Im trying to match it to my Coleman camper but cant see where each wire goes. Can you help?? does it follow the diagram on your website for 7-way connectors?

The pins on the Adapter 4-Pole to 7-Pole Vehicle End, item # 30717, and the pins on the trailer connector should be wired the same.

If you are just wondering what to connect the loose wires from the adapter to, they are, White is the ground, Black is connected to the battery of your vehicle through a 40 amp circuit breaker, item # PK54540, Blue is connected to the blue wire on the brake controller and Yellow is the the optional auxiliary function or it can be connected to the reverse lights, I hope this helps, but if that was not what you are asking, please let me know. I made a picture to the right that illustrates the functions of the different color wires also.

Keep in mind that you are looking at the connection points inside the trailer connector that the wires hook to. If you still are not sure use a circuit tester, item # PTW2993, if needed to match the connectors.
