Heat pump furnace wiring to new thermostat

I had a Honeywell Provision IAQ system. The thermostat only had red, white, blue connected. From what I have read this thermostat communicated to the Equipment Interface Module, from there signaled which equipment was to do what. I have pictures to post of wiring to the EIM before. I just want to make sure I connect correct wires to the new thermostat. I ran heat pump yellow, green, red, white, blue to the gas furnace board to respective colors and splice Orange straight of to thermostat. Could someone help me out by looking at location on EIM board and tell me which wires go where on new Honeywell RTH7600D thermostat?

Welcome to the forums.

1) Why are you changing the stat to that one ?
2) Do you have a heat pump and a gas furnace ?

If you have a heat pump and a gas furnace..... you have a dual fuel system. That takes a thermostat that specifies for dual fuel operation. That type of operation won't allow the heat pump and the furnace to run at the same time. Currently that function is controlled by that EIM module. As far as I can tell.... that stat is the wrong one for your application.
