Default 1991 Cadillac no ac econ only

Hello this is a project,...The previous owner replaced the old engine with a rebuild carburetor chevy 350. Great right. But took out all accessories . Im starting from scratch. No ac pump no bracket all vacuum lines are cut but there ..I think. I have the Cadillac "Bible " but it assumes that everything is there and few pictures . Is there a diagram with all vacuum lines in a illustration that are labeled? If someone could point me in the right direction I'd appreciate it thanks
oh and a way to get it to defrost, and turn off

Dealer service manual or some other service manual? If it is a dealer service manual, they often spread vacuum system information across sections. Sections 1, 6, 7, and 9 should have pieces of the vacuum system included.

The engine that was installed in it might not line up with brackets, bolt sizes, electrical, vacuum, etc.

Now is probably the right time to figure out the details of the 350 that'* in it.
