Vacuum ports for air horns

Can anyone tell me where the vavuum ports are located on the Cummins B engine?? Seens as if I seen in a post that they were located somewhere behind the brake booster. Just hung a set of Hadley twins on the bracket behind the bumper on the passenger side(same bracket the electeic horns are hung on the drivers side. I have a vacuum operated compressor and will need a vacuum port to connect it to.Any help would be appreciated!!
I do this all the time - I forget to say that the truck is a 94 Dodge 3500 Dually.
