Does anyone know where.... Vac question

Does anyone know where I can find a vacuum diagram for a 98 ml320?

Or.. can anyone look and see where the vacuum hose that runs off the back of the "manifold air pressure sensor" goes to??
It is located in front of the passenger side cylinder head it has a big "06" written on it in green. The vac hose on mine has broken off and I can't find the hose.

it goes on the front of the intake manifold.

just a regular hose straight to intake manifold? or does it link up with another hose or??
I cant find a unused hose, or anything unused for that matter off the front of the manifold.
Weird.
