The Trailer Breakaway Kit Battery Charger # 20011 is used to charge the breakaway battery on a trailer. The black wire connects to the tow vehicle's battery to get 12V, the red wire connects to the positive terminal on the trailer's breakaway battery, and the blue wire connects to the breakaway switch.

I made a simplified wiring diagram to show you how it gets wired in; I also attached a demonstration video for you.
