I understand your design used for 12V operation, but my goal is use truck inverter I already have with small cord.
virtually the same..refer stays in selected mode-AC or DC
Turning off campers 12v to refers controller keeps it from searching for alternate power. Turn it back on and it auto goes to AC.
Along with your AC line run a single ignition powered trigger wire to turn on refers added relay, at rear 12v main input to board.
Difference being in your case 12v would only power eyebrow and refer board, turning on and it goes to AC (when supplied). Mine goes to DC but same operation as far as truck control and no remembering to do anything once set.
End of day I turn inside switch to camp (powering relay with camper) set refer to gas or AC. Hitting the road, set refer to DC, flick switch to travel, relay controlled by truck. I 'could' run an AC line to refer and run on AC, utilizing existing switching no other wiring required. Describing more convoluted than doing...
But whatever makes since and you can visualize a plan, is the easiest. Probably several ways to do this. I simply didn't realize what I set up in our camper would also work for AC. Just options.
I'm not clear on how an AC relay would cause refer to come on
