993 non Vario-Ram vacuum pipes. help please

[robin993]

So I have a question. I have need working on the engine of my 993 non vario ram and during this noticed that one of the vacuum pipes was not connected, but i can't see what it should be connected to.
The poor quality photo below shows the problem. it is the solenoid valve that is mounted on the engine bay fan on the LH side of the engine bay. The lower 2 pipes were there, but there was nothing plugged into the top one, and i can't see any loose pipes to connect to it.
any ideas?
The Vacuum pipes on the manifold look fine to me with no obvious disconnections.

Any help will be appreciated.

I think that i have found the answer, nothing connects to the top pipe.
i found a downloadable workshop manual.

Sorry if this is a bit old. Just looking at mine now and wondering the same thing. Had a remap done and found the diaphragm faulty, leak in system etc. The link doesn't work, any idea if i can get it elsewhere?
