Replacing Trane XL802 thermostat with Honeywell RTH9585WF

[mhasselb]

I need to replace my Trane XL802 thermostat with the new Honeywell RTH9585WF I purchased. I can't find a wiring diagram that is the same as mine therefore I can't map the wires to the right place on the new thermostat. I've attached a photo of my current device (and wiring) and pic of the new wiring panel. Can anyone just map the 9 wires from my current set up to the right places on the new thermostat? Thanks in advance for anyone's help!

S1 and S2 are likely wired to a proprietary outdoor sensor you can no longer use with the new thermostat.  The new thermostat WIFI should gather the outdoor temperature, so you can eliminate those 2 wires.  You likely need to use one of them as your C wire now.  Disconnect it from the sensor and connect it to the C terminal in the furnace and then the other end to the C terminal on the thermostat.

X2 is the AUX wire (AUX/E) and B is the reversing valve (O/B).  There will be a thermostat setting to change the reversing valve to energize on heating or cooling.  You may also have to adjust the thermostat and cut off temperature if you're running a dual fuel heat pump system.  The other wires should just connect the same.
