Hello. Looking for a vacuum diagram for a 117.960 non-US/emission model with a manual idle control. (Circa 80/81)

I've searched high and low online but the resources are limited particularly when it comes to european models. Each of the years found (US) slightly differ from one another, most have electronic idle control, air pumps, exhaust pressure transducers, etc.

A scan or even a photograph of the 117.960 vacuum diagram would be helpful. Or if someone is intimate with the schematic, I'm hoping to confirm the following vacuum port connections, which can be plugged and which should have check valves/orifices present, if any:

EGR valve. Two ports.
Switchover Valve. Two ports.
Thermo Valves X2. Two ports each.
Ignition Distributor. Two ports. (Advance/Retard)
Throttle Body. Two ports ONLY. (Upper/Lower driver's side)
Intake Manifold. Two ports. (Driver's side, upward facing, next to throttle body/Pass side mid intake)
WUR. Three ports.
Shaped Contour Hose. Two ports. (Idle control)
Valve cover breather hose. One port. (Passenger side)


Any assistance would be greatly appreciated. Thank you.
