I have a functional diagram of the engine/tranny related vacuum system only it does not adress or include the ACC or Locking functions if that is what you are looking for!

If you give me an E-mail address I'll scan it and send it to you as an attatchment. Good Luck.

P. S.
I just checked my CD and 83-604 in the Automatic Climate Control Manual has the vacumm diagrams for that system!

80-010 and 80-900 in the Body Chassis has the Central Locking System functional diagram!
