Cant find correct vaccum diagram

Hello, I've looked everywhere for the correct vacuum diagram for my Euro 1980 500se lorinser however all the ones I find are different. it has no emissions, no thermovalve, 3 connection WUR, 2 connection vacuum advance, 2 connection switchover valve, 1 connection on the throttle body, 1 connection on the intake manifold. Does anyone have a diagram like this or engine with the same set up I could have pictures of?
