Vacuum connection-Where does it go?

@jsceash- Love the link you have on the post below with the picture, my question is where does the other empty tube goes from the tank-four way line.

Manual transmissions have a 3-way, the 4-way is for tiptronic. The extra line goes to a valve on the transmission. If you look at the diagram for the Air Injection system in the Katalog, it lists part "21" Y piece, and part "(21)" Distributing piece fourfold with option 249 (tiptronic transmission).

I can't seem to find the #2 Changeover valve for the intake, a line coming from the vacuum reservoir going into the Changeover valve. Found the first one on the driver side, can,t find the one on the passenger side.

It's at the base of the vacuum valve under the passenger side intake manifold. Item E in the part drawing. Mine is just behind the alternator, and beside the Bank 1 Knock sensor.
