A bit of help maybe?,

I am trying to put my 83 500 SEC engine back together and have not been able to find a vacuum diagram to go off of. The throttle plate has a vacuum switch on one side of it which looks like it has also melted at some point and it had a couple of hoses hooked up to it. (I also need this new vacuum switch)

I have the 1984 Federal vacuum diagrams which are what people have told me is probably the closest thing to what I need but it is not really helping, the US versions even show a throttle position switch which is something the Euro car doesn't even have so I am stumped. I did talk to a tech who was around back in the mid 80's when these grey market cars were hitting the shops and he said they were always somewhat in the dark as to what hoses went where as Mercedes did not release info on them and usually by the time they saw them they were hacked up with EGR's and other mods so any sort of factory advice probably wouldn't have done any good anyhow.

Thanks for any ideas.
