I have had a very hard time finding vacuum diagrams for older Saab's. So being a TERRIBLE artist, I decided to make the below image based on my 1993 Saab 9000 Turbo w/ Traction Control (TCS/ETC)
For my own enjoyment, I added the Hydrogen Generator that I am in the process of testing before fitment into my vehicle. This obviously can be ignored as it does not change the vacuum routing.
Also note: I have an aftermarket Greddy Type S Style Blow-Off Valve - The secondary port here can be put back into the system, however I have found it to work fine being vented to atmosphere.
I will also try to add in a Manual Boost Controller to the image for those wanting to know how that is hooked in - however my last attempt caused a boost spike of 1.6bar - so I am re-checking my vacuum for that.
