Below is a modest collection of Volvo vacuum connection diagrams I have located or created from Volvo service manuals and other sources. 
I'm always looking for more diagrams to help our fellow Volvo owners who are having a tough time locating these. 

Additional vacuum diagrams can be found in my Vacuum Label Collection here.
 
If you can help supply more Volvo vacuum diagrams, please write me.
