The Bulldog Powered-Drive Trailer Jack, item # BD500200, only has one wire, the power wire. This jack attaches to ground through the mounting hardware and the trailer frame. When wiring the jack to your 7-Way trailer connector you will need to make sure that the ground wire from the 7-Way trailer connector is attached to the trailer frame to provide ground. You will then attach the power wire to the 12 volt accessory circuit inside the 7-Way connector or splice into the wire the is attached to the accessory circuit. The photo at right shows the connection point for 12 volt accessories inside the 7-way connector.

The preferred method for installing this jack is to use a secondary battery, but you can also use the accessory circuit of the 7-way if needed.
