I would like to have the option of turning on my running lights when the camper is not plugged into my tow vehicle but is plugged into shore power, (or running from the camper battery). I have a Mighty Mini PD4200 not wired in yet. The running lights wires would need a jumper wire to fasten to one of the 12v accessory ports on the converter. The running light wiring otherwise is standard and running to the 7 pin connector and running lights. My concern is what happens when the shore power is disconnected and the 7pin is plugged into my truck and then theoretically I'm running 12v backwards into the converter. I've thought about a simple switch that would disconnect the jumper before hooking up back up to the 7pin. I dont have an isolator switch in my plan yet and probably should on one regardless, and wonder if that would be part of the solution. any thoughts or other ideas? TIA
Splice into your running light wire at the tongue J box with an auxiliary wire. You can put a plug on the open end or run it to a switch. Connect another wire to the battery hot and fuse it. Run to the switch or install a plug to connect the other wire. Personally, I would use plugs instead of a switch to make it harder to see and connect. Once unplugged, both can be capped and stowed out of sight.
NOTE: do not plug the running lights into the battery if the 7 way is connected.

There is a way to wire a receptacle (tow vehicle) end with a switch, you plug in your trailer into it and turn the switch on. Also you can wire a standard auto turning blinker and make your lights go on and off. I saw this on a rv website, can’t remember where.
