Hovsep:

Try 07.3-230 in the cd manual.  This shows the throttle valve body with 
the (3) vacuum lines going to  1. lower chamber on the warm-up 
compensator, 2. 4 point distributor and 3. to reservoir for full load 
enrichment on the 84 500SEC.

The rest of the vacuum diagrams are, from what I have referenced in the 
past, distributed throughout the manual based on the component you are 
testing or working on.  I have not found a global overview of the vacuum 
lines and controls in the manual.  I agree this would be most helpful.  
Has anyone got such a resource or perhaps I've missed it in the cd-rom 
set that I have, anyone have the whole configuration for vacuum on these 
engines???

Regards,

Dick
