There should not be 12 volts coming out of your ground terminal (7:00) on your vehicle connector. That sounds like where your problem is located. It sounds as if the 12 volt accessory that should be in the 2:00 position of your connector has been mistakenly wired to your ground circuit.

I attached a picture of how the connector on your tow vehicle should be wired by function for you to check out. I also attached an FAQ page on trailer wiring that you might find helpful.
