To connect the Roadmaster Battery Charge Line Kit for Towed Vehicles # RM-156-25 to your tow vehicle, you're going first want to mount the included circuit breaker with the included self tapping screws.

Next, you're going to want to strip the ends of the red wire that comes in kit, and crimp on the ring terminal.

Now, you'll want to connect one end to the copper post on the circuit breaker, and run it to and connect the center pin on your 6-way connector.

Finally, you're going to want to connect your battery to the silver post on the circuit breaker using the last included ring terminals.

You'll want to do this live so you aren't working on a live circuit.

I have included a review video of # RM-156-25 for you to check out as well.
