Vacuum Hose-'95 3.8

Found a long vacuum hose that somehow became disconnected. It hangs down from under the drivers-side windshield wiper (under the hood). Can't see what it's connected to up there, but the other end isn't attached to anything.

I'm guessing the free end is supposed to be connected to a vac source, but where?

I had a look under he hood. The only hose I did find in that area was the hose for the windshield washer. If it is not that hose, I need a photo to be able to help you.

Thanks! Here it is:

Found it. Looks like I had previously removed the WW washer tank and forgot about it.
