Ok so I printed off both wiring diagrams for an auto and manual hvac circuit off of MitchellOnDemand5 from school today.
At the moment I'm sitting here with a highlighter figuring out what the auto circuit has that the manual doesn't. If anyone has any other info on this it would be appreciated. I'll post the results of my highlighting when I'm done.

Looks like a few modules and the IPM is different, not sure if the car would swap easily
from my expierence all the extra wires that the automatic has won't be there and have empty connectors to plug in to, I have always had to add my own pins to connectors and run new wiring

Ok well it went well at first (I started with the 2nd page) but most of the stuff on the 1st page is different.

Looks like I need:
Instrument panel module
HVAC control module
G201 (x2) [I'm assuming this is a sensor?]
Recirculation Actuator
Air temperature actuator (L & R)
Mode actuator
Air temperature sensor (x6)
10A Fuse
And lots of wiring and harnesses
