Exclamation engine vacuum

Is there anyone who can tell me where the fuel regulator vacuum lines should go on an 84 euro 500 sel? I have been trying to buy,beg,borrow info for a month with little success. The autodata diagrams as well a the chiltons show a different number of vacuum ports as well as several different components. This sel has an egr valve, no o2 senser or lambda controller, and only has one small vacuum port at the throttle body. It had a full throttle vacuum switch on the throttle body that was disconnected.Currently the distributor(with only one vacuum nipple) is connected to a small manifold port just on the drivers side of the fuel distributor. There is also a clear with blue stripe vacuum line that is disconnected near the front of the manifold that is connected to one of the check valves by the fuse box(yellow check valves that go through the fiberglass barrier in front of the fuse box). Any help would be greatly appreciated.
