I am restoring a 240 D and presntly my vacuum circuits for my Door Locks and Trunk Lock dont work correctly.

What I need most is a diagram of the system, I cant find one. I checked the Service CD and there isnt much.

Does anyone have any advice as to the key failure areas, troubleshooting advice, or documentaion such as diagrams?
