Vacuum system for the 4x4 transmission/ transfer case & differential?

Have a 1983 S10 Blazer 4x4 that has vacuum lines on transfer case that are torn loose. Also under the hood is a vacuum diaphragm that leads down to the front differential. It had been disconnected. Need information as to how they are connected & operate.

Thank you for any assistance you can provide.
