So I'm in a coachmen 2002 travel trailer and I'm replacing the duo-therm relay control board for the rooftop ac to a dometic and I need help with the wiring because the wires for the old one is not the same as the new one and the rv place didn't give me any directions on how to do this. They just sold me the darn relay control and new thermostat please help. Can provide pics if needed thanks in advance!
