Valve Cover Vacuum Lines, N55

[dennisvab]

I had a vacuum line randomly fall out of the valve cover area (exhaust side of engine). I had to take my valve cover recently and see that there are two spots for vacuum lines. One spot is for the pressure converter, and im guessing the other will take the line that fell off because it cracked.

The problem is, i dont know what line goes where. This image below makes it more confusing, because it refers to one spot as a "reserve"
