Why? Is there a reason for this? I've been looking for days and can't find a definitive answer. The AT and MT version both have the same Brake Booster part number, but one gets vacuum from the intake Manifold (MT), and the other gets vacuum from the Cam-driven Vacuum Pump on the rear, passenger side of the engine (Where the leaky cam plate is on the MT version). But why?

What's stopping me from just using the plugged port on the intake manifold for brake booster vacuum? If nothing, then why have the pump at all?
