Vacuum Diagram

Hi, I'm looking for a vacuum diagram for our 91 grand prix. Someone took a screw and put it on the hose so now we are looking for where it might possibly go but can't see to much in the back of the engine and we really dont want to have to take the heads off. We also found another hose and can't find where it leads as well so a diagram would be great help if anyone knows where to find it.
Thank Cammy
