Wiring thermostat help needed; Amana1213404 to Honeywell RTH7500

My old thermostat is Amana Model 1213404. This is how it was connected;
black wire to c
green wire to g
orange wire to o/b
yellow wire to y
red wire to r
white wire to w2
blue wire to e

My new thermostat is Honeywell model RTH7500
It has connections
c
g
y
o/b
rc
r
aux
e
l

My Amana heatpump has electric aux heat and emerg heat.

How do I connect existing wires to new thermostat?
Many thanks.
Tony

Glad to help!

On the advance sat up, I'd suggest these settings.
170-7
240-3 (may not show up)
270-3 (I know book says 9, but really it means cycles per hour)
