The HVAC vacuum hose should be connected to the line that runs to the vacuum ball. You can tee into this line if the connection is no longer there. If the vacuum ball is missing, you can connect directly to manifold vacuum, but your HVAC performance will be suspect, with the vacuum going up and down.
