'99 Solara - Hanging Vacuum Hose

1999 Solara SLE V6 3.0 - Vacuum Question - Just bought Solara for my son. Previous owner installed aftermarket air cleaner. I found a vacuum line coming off of the VSV for the EGR (single port end) that is not connected to anything. The engine label diagram appears to have it connected to the air cleaner. There is no port/adapter on the aftermarket air intake tube for this line. Question(s): Is this line suppose to go to the air cleaner? If yes, can I simply install an adapter onto the air intake tube and plug the line to it? Does this line simply draw air from the intake tube, or is there another valve involved where the OE air cleaner box should be?

Thanks for your assistance, and sorry for the long question.
