Trying to install this and the wiring harness is different. The refrigerater thermostat has four wires, one of which goes to the damper, the new wiring harness has three.
With the redesign of the part they eliminated the wire that would normally go from the thermostat back to the damper motor. This is now routed through the ADC board. You will want to put the black on the left side and green to ground and the other wire to the other outside terminal. Turn on the unit and test it as it may be necessary to move the white/purple to the other terminal.
