    How to hook up a 4 wire themostat to AC unit on camper
    Yes, I have a coleman AC unit on a 94 wilderness. The colors from the thermostat are black, green, brown, and white. The colors of the wire coming from the AC unit that attaches to the ceiling to the unit are Black, blue, gray, and white. My problem is (oh, I also have a 12 volt wire I don't know how to hook up), when we disconnected the unit to replace the rubber roof, we lost where we wrote down how to hook the 4 thermostat wires back to the 4 AC unit wires. Please help.
    Thanks,
