1977 450SL

I searched but am having a hard time finding the appropriate vacuum line routing for my warm up regulator on my new 77 450SL (Ca. Car).

The previous owner has the vacuum disconnected from mine and I need to see where they hook up to correctly, the web has various pictures but can't find a nice close-up of where the lines go.

Car starts and runs great but it seems when it gets to operating temp it acts like its loading up with fuel, nothing major but it seems a good place to start is the proper hook up of the vacuum line to the WUR, possibly its not Closing or turning off? If that makes sense.

Any help appreciated.
