The stock end plate has two vacuum lines/ports, plus now there is a vacuum line to the blow off valve. In Dinan kit the three lines all connect to one nipple on the back plate using plastic adapters, which I thought was a bit messy. So I added two more connections in stock locations on the plate dedicated to the two stock lines and will use the other connection for the BOV. The sensor in the middle is the boost pressure sensor.

I drove about 60 miles to the office and back on Friday with the catch can and when I removed it later that evening, the inlet hose had was just a bit oily, while the outlet was completely dry. It seems that at least at this point oil out of the crank case is not a major issue, but the catch can will help almost completely eliminate any oily fumes from the intake, which I think is a good thing, so I decided to put it in.

EDIT: just remembered... when I removed the aluminum PCV pipe under the manifold, there was some oil in it. So the catch can will certainly help.
