I removed the 4 wires from my thermostat and the 2 wires from my A/C unit from the control board ICM 271 and seem to be having trouble getting them back to the proper places. Control board has C-Y-GC-GH-R-W and the thermostat has RH-RC-W-Y-G and the 2 wires coming in from the A/C unit are both black. Thought I could do this but guess I should have taken pics first. Any help would be great. Thanks.
