Default Heater A/C controls

I have a 65 GTO w/ A/C. I have never used the heat. I have a valve closing off water to heater core.
I tried to use my heat and opened the valve. Apparently I never attached the cables to the heater box.
My question is there 2 or 3 cables from control to box. Is there any sort of vacuum needed to facilitate operation of heater???
Think I can access cables and box by removing glove box?
