It has no vacuum hoses compared to the oldsmobile 307 in 1986-1990 broughams. Now that is a confusing motor to figure out with messed up vacuum hoses.

You could always go to AutoZone's web site to find vacuum diagrams. They should have what you are looking for, or go to your local Chevy dealer, not sure if your local Cadillac dealer's repair department would help you out.
