If that hose comes off the top of the factory WG body, it should be "open to atmosphere" so that air on top of the diaphragm is not compressed, allowing free movement of the WG valve. It is usually routed to the airbox or otherwise arranged so that small birds don't nest in it...

If that hose comes off the middle (side) of the factory WG body, it's supposed to be the boost signal, and should be connected to the pressurized portion of the intake somewhere. Without it connected, there won't be any boost regulation (WG won't open because it'll never "see" the boost).

If it's an aftermarket WG, check what the manufacturer says the ports do...
