The short answer is none.

The diagram that JR posted up, does identify vac lines as A/C the way Ford did, but they can be more accurately described as Climate Control.

That vaccum source is what lets you choose between defrost, vent, and heat outlets when your blower is on. If you were to remove that vac, your air/heat would only blow out the defrost.
