Manifold Vac Port

Cleaning up some vac lines. What port is this? On the manifold just in front of the ERG switch.

They only work if vacuum is applied, as they are now, they are dead and useless.

The lines mostly tied back to the 5 port for the EGR or back into each other. I was just wondering what they originally were supposed to control.
