If you look at the front of the 7-way on your motorhome the pin in the 1:00 position is the 12 volt accessory pin. You would want to run a wire from the positive side of your motorhome battery through a circuit breaker like part # 9510 to the 1:00 position of the trailer connector and you would be good to go.

I would recommend 10 gauge wire like our part # 10-1-1. This is sold by the foot, so you would need to order a quantity of how many feet you would need.
