The only vacuum schematic I have for emissions is attached below. I'm not sure if you need the interior HVAC control or not, but I attached it as well.
As far as the attachments, pic 1 is for light-duty emissions, pic 2 is for heavy-duty emissions, and pics 3 and 4 are the air flow directions for the HVAC.
Let me know if this helps.
See pics below.
