Expert Reply:

I have attached a photo that details the wiring connections for a 7-pole round pin connector. It also includes the vehicle side wiring as well. I have also attached a photo of the 7-way blade style connector as well. The center plus is an auxiliary 12V circuit.

I do recommend using a circuit tester like part # 40376 and test each wire on the vehicle to make sure you have the correct configuration on your connector.

I have also attached a link to a helpful article about trailer wiring you can check out.
