I would like to get rid of my TAYPLUS103A which is malfunctioning. I recently purchased a new VP IAQ with outdoor sensor for HP lockout. I am a little confused on wiring.

My HP has the following connections:
T (not used)
O
X2
Y
R
B

My furnace control board has the following connections:
G
W
R
C
Y

Questions:

Do I wire both the HP Y connection and Furnace Y connection to the VP Y connection?
Do I wire both the HP X2 connection and Furnace W connection to the VP AUX connection?

All the other connections and stat programming make sense. Thanks for your help!
