Old to New Thermostat

[Barretrahl]

Okay, I have a AC system the date on it is 4/90 and it states that it is a packaged heat pump. I can find no company name, just HQCO lavergne TN. I can find no information, diagrams, manuals.

The outside wires are labled R G W1 W2 C O Y (There is a jumper from W1 to W2)

R- Red
G- Green
W2-Light Blue
C- White
O- Orange
Y- Yellow

I tried to label the wires inside, but they did not match the new Hunter Thermostat I bought for a heatpump. They are labled
G RC RH Y/O W/B Y1

I just need to know what's what, I can find no way to cross-reference, nor can I find anything for the outside wiring either. If anyone could help me out it would be greatly appreciated.
