Heres the pics you wanted matey. There are two seperate vacuum systems on the E16SE (1.6 non cat GSi engine).

The first picture shows the coasting valve. This is supplied by a vacuum pipe comming from the right hand end of the inlet manifold. The pipe splits off and also supplies the fuel pressure regulator.

The second picture shows the temperature controlled vacuum valve that sits on the ally block on the back of the manifold (also has the coolant temp sender in it). A vacuum is taken from under the throttle body and goes to this sender, then it goes to the EGR valve.
Hope this helps
