Vacuum lines -- where do they go?

Time to plumb my NSX motor. It's supercharged, so I can't run vacuum lines into the intake on the pressurized side of the supercharger. So where does it go? Just to the non-pressurized side, on the intake that leads to the supercharger? I figure that's where it would go, but cars are nuts, so no tellin' what the reality is.

Found some quick photos of a supercharged nsx. Not sure if you meant roots or centrifugal..
