CHEVY VACUUM HOSE DIAGRAM

Recently work was done to the intake manifold by a GM dealer. The vacuum hoses were not put back in their proper place. This has been rectified as the hose layout is shown on the radiator cowl. The problem is there exists a vacuum damper valve located near the EGR solenoid with 3 ports or hoses to be attached. One of these hoses goes to a vacuum cable assembly (cruise control??) above the battery, another to the last port on the air plenum reserved for the HVAC, the third??? I can not find any info on the proper hook up of this damper valve and its 3 hoses.

I will email what I have, but my advice to to complain at the shop that did the work, tell them the work is shoddy and needs to be done right. You did pay for it.
