Do you agree the breakaway switch being hard wired would be better?
When are you expecting your camper to arrive?
Dredging up an old thread here now that I've had an opportunity to inspect mine.
If yours is like mine, it has a circuit breaker on the positive wire, just under the front of the trailer. The breaker is the big red capped thing on the left of the image. The front of the trailer is down.
The wire from the battery runs there but is first split to provide current to the breakaway switch at the bottom of the two connectors, with the red and black wires. The top connector is the return from the breakaway switch that connects it to the blue brake wires.
To add a battery disconnect switch on the red wire, the hot side of the breakaway switch must be cut and attached directly to the red somewhere before the disconnect switch. Even the hot side terminal on the disconnect switch would do.
Always remember to cap off any wires you cut, lest they cause mischief when you least expect it.
I haven't decided on my battery configuration yet. I can see two main options. 1. Having two 12V batteries that are not connected to each other so I can remove one for charging while the other powers the camper. 2. Two 6V golf cart batteries, they will fit nicely on the tongue.
