1991 Mitsubishi Galant Vaccum Hose

I have a vaccum hose coming from some type of module on the Passenger side corner under the hood. The vaccume line is connected to the module but it has come lose at the other end and I cannot locate where it connects to. I also have not been able to locate a vaccum diagram anywhere online to view.
Can you tell me where that line is suppose to connect or the routing for it or provide me a exploded view of the vaccum routing diagram.

Thanks!

Bill
