I don't know for sure. I would guess: vacuum accumulator tank fed by common vacuum signal as Tony suggested. Even the 993 3.6 has an accumulator tank. On the '95 it is under the spider manifold and about the size of a can of baked beans.
I've seen electric vacuum pumps w/ a small accumulator tank, too.
Good questions.
