HVAC Controls: No heat

So I recently did a 302 conversion and it running absolutely awesome. I'm just getting the little stuff done on my car and getting the HVAC back up and going. I have all the AC stuff from my donor car that I plan on reinstalling soon but first I'd like to get the heater going.
The heater worked with the 2.3T but since the swap it hasn't, The controls work and the blower motor gets going but it seems like the blend door isn't going to the correct position. Basically I just need to know what exactly lets the HVAC panel run correctly, and where it usually comes from. Vacuum, Wiring??
I have all the schematics printed out but I cant figure this one out.
Also do the late turbo coupes have vacuum reservoirs?

You must have the automatic climate control. Both of my 86's have the manual controls and they use a cable to move the blend door but there is a vacuum connector as well. Sorry if this doesn't help.

Yes it is the auto climate control. I'd actually like to convert to a manual panel in the future.
