126nut,

I don't have what you want either but maybe can help you sort out some of the lines.
My 500SEL is a US car but has a Euro engine that actually came out of Mexico (or so I was told). I have never seen a gray car that had all the required emission equipment that actually worked. The cat was always there as it would be inspected. The frequency valves never worked, only had wires going to them.
Let me suggest you take the vacuum diagram you have. Mark out anything you don't have, for instance you probably don't have an air pump. Mark out the vacuum lines for that system. You don't have a place to connect the switch (idle/WOT) so mark it out. I don't have a vacuum switch on the TB so I'm not sure what that is about, but mine does have a ported vacuum port on the TB. Maybe that is what you are seeing. When you get everything marked off that you don't have, hook everything else up using what you have left on the diagram.
In reallity, if you hook manifold vacuum to the dist vacuum advance and plug every thing else so you won't have any vacuum leaks the car will run great.

If you have any questions, let us know.

Paul
