Need help ASAP on R16/1 and vacuum advance

[Joseph_190E]

Guys,
I've read all threads on the topics above.
I need to located them and can't?

I have a 1992 190E 2.6. The R16 is suppose to be around the intake manifold but I still can't find it? Others have suggested around the battery and the fuse box. Still nothing found

As far as the vacuum advance is that the line from the intake manifold to the ignition module? I believe the ignition module is attached to the fender and has 4 round plugs attached to it?

Pictures would be nice since they do say 1000 words.

I need to located them to pass my smog. Help

thanks,
joseph
