Update - Got it wired. I was able to reroute the wires up to the control box. Routed the 2 furnace wires up from the old thermostat. Routed the 12V+ up to it and the routed the 3 wires that hook to the thermostat. Have it all hooked up but the thermostat doesn't display. I checked power and there is 12V at the small 12V screw so I know power is reaching the thermostat. I checked continuity between the 3 wires back to the control box and there is. No display. I have the Dometic Capacitive Touch thermostat. I called Dometic - No help at all. I think the thermostat is bad since I do not get a display at all. Any ideas?
