E34 Vacuum Line's

[xaviervp]

Does anyone have a vacuum line routing diagram for 1995 M50 E34's,
In the front passanger side of the valve train cover there is the PCV or crank case ventilation fitting, it has for two (2) hoses thick and thin.
The thick one I was able to replace it because it was still in place though it was cracking into pieces but the thin one I have not been able to locate where it goes.
I went to our local dealer and the vacuum diagram the parts dept has didn't show where it went to.
I tried asking service and they wanted me to leave the car for service with a min chg of ($125.00) if I choose not to repair just a diagnosis of the problem that didn't exist I just wanted to know where this hose goes, if I let them repair it it would still be ($125.00)
I hate to have to remove the intake manifild to identify where it plugs into.

PS: I looked at realoem.com and it doesn't show where it goes either.

Any help is greatly appricated.

throttle body?

It connects to No. 9.

It connects to a connector that connects the Idle Control Valve to the intake manifold (underneath the manifold when looking from the top of the engine.) The connector is not very easy to see , unless you happen to have the manifold removed from the car.

You can feel for it this way: Reach under the manifold near the center (below where the throttle body connects toward the intake runners) you will feel a large robber hose connected to the Intake. At that connection point, there is the place that the vacuum hose connects.

Here's a picture of the connector, happen to have an extra on my desk:
