The Brake Controller itself is connected to the battery in the tow vehicle.

The breakaway system battery is good for a month or two of inactivity before needing charging. The Break Away kit you looked at, the Tekonsha part # 2028 includes a charger that will keep the battery maintained during towing. The charger is supplied power by the 12-volt power circuit from the 7-way trailer connector.

I will provide instructions that include a wiring diagram. You can see the instructions by following the link below. We also have an installation video, which you can view by using the link below.

I also included a link to an FAQ page on brake controllers to the right for you to check out also.
