There are a number of Factory Service Manuals for the '75 on ebay....#25/up. Vacuum diagram will be in the manual along with everything else about the vehicle and it's systems. Best 'tool' a diy'r can have....a FSM.

Usually, there is a decal on the radiator support filler that has the vacuum diagram on it. I'm guessing that it is non-existant on your car. If that is the case, a factory service manual is your best bet. You might also want to take it to a Cadillac dealer - some of them love seeing the classic cars in good shape and might route your vacuum lines at no charge.

Thanks for the feedback.I was trying not to buy a manual as this engine now lives in a 1973 Jeep 4wd pickup.I have searched everywhere to find just the diagram but have found nothing.Looks like time to buy the book.Thanks again,Marc

Another thought is if you cound find one in the junkyard, you could copy the diagram from the junkyard car.
