Hi! I've installed a Phoenix 12/375 inverter in my vehicle. I'd like to add my own toggle switch with indicator light in a more accessible place. All toggles with lights that I've seen have three terminals, two for circuit to load and one for negative, but the remote wiring only provides 2 wires and I don't know the voltage. Is there anyway to install my own switch that lights up when on? Does Victron make a remote switch that's much smaller and recessed into the wall perhaps? Thanks for any help.
