Do you have the vacuum diagram?
Yes, I'm pretty sure those squares you mentioned are the vacuum lines for the HVAC system.

The under hood vacuum diagram will not show vacuum lines for the HVAC system. The best you can hope for is, the diagram to show the one vacuum line that runs off to feed the HVAC system.
