Hi,

If you look below, I attached the vacuum schematics from my manual. The first two are related to the emissions/engine system. The last pic is for the HVAC system which parts of it are controlled by vacuum.

Let me know if this helps or if you have other questions.

Take care,

Joe

See pics below.
