Coleman 3300-378 Thermostat


Hello, I have an old Coleman 3300-378 thermostat (3AAT82B13E1) on a Coleman 3300-815 system that I am trying to install a higher efficiency thermostat on. The thermostat I am trying to install is a Honeywell RTH7600D. I am having difficulty matching up the wiring for the thermostat. The current wiring is as follows:

R (red wire)
A (brown wire)
W1 and Y1 jumped together (yellow wire)
X (orange wire)
W2 (blue wire)
V (white wire)
G (green wire)

So on the new thermostat there are connections:

C, G, Y, O/B (or W), RC and R (jumpered together), AUX (or W2), E (or Y2) and L.

I believe the connections should be as follows:

Old------------->New
R--------------->R and Rc (jumpered together)
A--------------->Unknown (possibly O/B?)
W1 and Y1------>Y
X--------------->C
W2------------->AUX (or W2)
V--------------->Unknown (possibly E?)
G--------------->G

Does this sound right? I have searched ALL OVER the internet without luck.

Thank you for your help,
Adam
