, posted Thu 17 Nov 08:36  
We have a Goodman ARUF04200A1B Furnance (NEW) and an existing Coleman Heap Pump and Coleman Thermostat. Trying to wire thermostat into furnance and into heat pump. Any idea as to what wires go where? I have the schematic of the heat pump and the furnace but getting confused as to switch colors match wires. I have a gray wire coming from thermostat and don't know where it should go. Just getting heat from furnance now and not any service from heat pump.
Our 3600-3681 Thermostat wires are O, X, B, W2, L, R, E, T, G, but there is also an S1 and S2
I have orange wires and don't know where they match to the furnance. If I find more I'll post again. Any help with this will be greatly appreciated!

the orange wires should tie together at the air handler, no connection to indoor unit, also the yellow wire will tie together at indoor unit, probably no connection to indoor unit. Some of the older coleman heat pumps are very specific in their wiring, did old unit hook up to outdoor unit with a cord with a plug on the end? If so you are going to be in for a wiring nightmare to make it work with that Goodman unit.....
