I have an 84 z31 turbo and I am badly in need of a complete vacuum schematic. Can anyone assist me with this or direct me to a good source to get this information. The car runs fantastic, but I need to get the a/c and other items working properly so this is my immediate place to start. Any help would be appreciated.

 

i also have an 84 z31 - I have a vacuum diagram. I could mail you a copy if you like.

 

xenonz31.com has a copy of the complete service manual for download in the reference section. helped me a lot.
