Need help with wiring a Honeywell RTH9580wf Thermostat.

Hello everyone,

New here and need some help/info.

I am trying to wire a new honeywell t-stat to replace an old York Mercury thermostat. I have a heat pump as well as an electric furnace.

I am having some problems with the wiring. Nowhere I find what my wiring looks like.

The first picture is the current (old) setup. Second pic is inside my furnace...

Thanks for the help

Old = New
G = G
R = R
W = Aux/E
B = C
X = I'd tape this heat strip wire off in my area but connect it to Aux/E if up north.
O = O/B
Y = Y

Configure for heat pump with Aux heat.
Energize the reversing valve to cool.
