Question:

With the Zip two wire breakaway switch, one wire goes to the terminal in the Bargman 7pin box for the trailer brakes blue wire from TV harnes. Where do I connect the other wire to receive power from the TV battery? Thanks for any help.

One of the wires that runs to a trailer breakaway switch goes to the brake output circuit of the trailer wiring which is what activates the trailer brakes and the other wire runs to the breakaway battery output wire which both of these wires are typically blue but not always. I attached a diagram that shows how it all gets connected.
