Honeywell RTH7600 wireing

Just got the Honeywell RTH7600 and don't want to FUBAR the unit, or blow fuses, etc, etc...

I have a Trane weathertron heatpump with aux. heat made in 1993 (date on air handler)


The old mercury stat has the following
R-red
T-brown
O-orange
G-green
Y-yellow
X2-orange
B-pale green
W-white

NOT USED
F
U & W are jumped



RTH7600 has the following (I assume you have to use the ones labeled "Heat Pump" and not use the "Conventional"
C
G
Y
O/B
RC
R
Aux
E
L

R & RC are jumped and remain jumped and I connect the red wire
No T...where does the brown wire go?
No O...where does the orange wire go?
G - I connect the green wire
Y - I connect the yellow wire
No X2 - where to connect the other orange on W2 or Y2?
No B...where does the pale green wire go?
W - I connect the white wire.

Think I have to use the alt. wiring

My R (red wire) to - R on new stat
My T (brown wire) - don't know where it goes?
I have a O and a B...so
My O (orange wire) to - O/B on new stat
My B (pale green) to - C on new stat...is this the common wire?
My G (green) to - G on new stat
My Y (yellow) to - Y on new stat
My X2 (another orange) to - E on new stat?
My W (white) to - Aux on new stat?

Do I have X2 and W and the O and B correct?
Where does my T (brown) go?

Thanks
