Vacuum hoses...was Re: Warm intake issue

[eric chase person <eperson@students.uiuc.edu>]

speaking of this vacuum-controlled airbox flap, where does the hose
leading to this draw its vacuum from?  Is it the purple hose from the back
side of the intake boot?  I am going to be replacing all my lines soon and
the diagram in the engine bay is crappy,and Bentley doesnt give us
anything in the form of vacuum routing diagrams.  Anyone have a good
diagram of the hoses and routing?
thanks,
