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?
