Goodman Janitrol 3AAT86B21A1 to Honeywell RTH5160 series

Hello, I have an old Goodman 3AAT86B21A1 thermostat and I am trying to hook it up to a Honeywell Home RTH5160 series T2 non-programmable thermostat. Model # RTH5160D1003. My Goodman is hooked up the following way:
Terminal wire color
Y-yellow wire
G-green wire
R-red wire
O-orange wire
W2-white wire
E- Blue wire
C-brown wire


On the new thermostat there are ports labeled Y, G, R, E, and C. So, my questions are:
1.) Will this Honeywell work with my existing system?
2.) Do I match up the wires for the Y, G, R, E, and C ports exactly?
3.) The new thermostat has a port for O/B, so do I hook up the O wire from the Godman to that?
4.) The new thermostat has a port for aux or W2, so do I hook up the W2 wire from the Godman to that?
Any help is greatly appreciated.

Welcome to the forums.,

That's a basic no frills thermostat.
It will require batteries.

Y ----------> yellow --------> Y
G ----------> green ---------> G
R ----------> red -------------> R (put switch in single R position)
O ----------> orange --------> O/B
C ----------> blue ------------> C
W2 --------> white -----------> AUX
E -----------> brown ----------> E

You'll need to make two programming changes....
200 - heating system type -----------> 2 Heat Pump
205 - heating equipment type -------> 7 Air to Air Heat Pump
