question on 95 E320 intake switch over valve vacuum source
 

I pulled the intake manifold off of this one not too long ago and now during reassembly I am unable to find the vacuum line that used to connect to to the switchover valve underneath the intake. If anyone could provide info regarding where this is supposed to be sourced from I'd appreciate it.

It gets vacuum from the intake, being mounted into it. There should be a short piece of vacuum line connecting the two halves of the switchover valve assembly, IIRC
