Can anybody help me? I am replacing the rear AC unit on our 2011 Montana 290RLT. I accidently pulled the wires from the Control box prior to documenting their locations. The control box has B- Y GH GL W The wires coming from the thermostat are RED GREEN (WHITE or LITE GRAY) and blue...
Additionally, the blue wire is joined to a much larger white wire. I'm totally confused and cannot find any help on the internet and don't want to ruin this brand new expensive AC unit. Any help would be much appreciated.
