merc 300d

I have a 1979 Mercedes 300d with a vacuum problem. It has 5 vacuum pipes coming through the firewall and all disconnected. Only the brake booster is connected to the vacuum pump. The door locks don't work as well as the engine shut down which I have to do manually shutoff. I looked at many forums for vacuum system diagrams but they all for overseas models. Some pictures would be greatly appreciated.
