HELP! Replacing old Weathertron T-stat with Honeywell RTH6360D
Can someone please help? My old weathertron heat pump T-stat has the following wires:
R
T
O
G
Y
X2
B
W
I'm trying to replace it with a new Honeywell RTH6360D Thermostat but not sure where to connect the B, X2, or W wires to on the new T-stat. On the new stat: will B go to C; X2 go to Aux or E; W go to W or E?

Welcome to the forums.
Turn power off to air handler before rewiring.
R -----> red ---------> R (1 wire)
T -----> brown ------> tape off
O -----> orange ----> O/B
G -----> green ------> G
Y ------> yellow -----> Y
X2 -----> gray -------> E
B -------> black ------> C
W ------> white ------> AUX/W2
System setup options..... you must change these two or your system will not operate.
# 200 -----> 2 - heat pump
# 205 ----->7- air to air heat pump
I must be getting slow

I am putting this electric furnace in a mobile home. It is old, but has been in storage unused for decades, so I have no manuals. What size copper and breaker(s) do I use?
