matching the wires

I need wiring instructions. I have a Trane Weathertron thermostat and I want to replace with a Honeywell RTH7400. The Trane Weathertron terminals are as follows:
B= Blue
X2=Black
W= White
T= Brown
G= Green
O= Orange
Y= Yellow
R= Red

The Terminals on the Honeywell RTH7400 are:

C
G
Y
O/B
AC
R
W2
Y2

I need to know which wires go to the RTH7400 terminals
