The air pump has a clutch that engages the air pump when the car is first started up to pump air in to the emmisions system. You are indeed correct it is attached to the belt system. Disconnecting the plug will disengage the air pump clutch and so it will be disengaged and should not engage the pump unless the clutch itself is trashed.
