The two leads from outside go to C and Y1. The yellow from thermostat attaches to the Y1. The light blue is C Red goes to R. You should have a G terminal on furnace that the light green or G goes to. Russ

What color wires are on outside unit. Russ

Do you have G terminal on board. Russ
On the thermostat board? I will have to pull it apart to check that out.

no G terminal, and I will try it out as you described. Thanks Russ!
