    It's a huge difference. That is your main vacuum port. It isn't supposed to be switching anything. Thermal vacuum switches divert vacuum when the engine reaches a certain temperature, and usually go in one of the coolant fittings in the front of the manifold or in the top of the thermostat housing.
