My 924 NA has a turbo warm up regulator, but how should I connect it to the intake manifold? Do I have to buy one from a 931 now?

Who can help me?

To get the full throttle enrichment part of it functioning...hook-up to any vacuum source downstream of the throttle valve.

I do not know about the turbo WUR but the audi WUR has to be connected to the same pipe as goes to the ignition distributor (the pipe is before the throttle).
Otherwise it would be enleanment instead of enrichment under load...

No, the WUR with full load diaphragm's vacuum line hooks up to an intake manifold vacuum source downstream (after) the throttle valve. Here <click> is the vacuum line diagram for an '80 931. It has 2 vacuum lines to the distributor. The one that the WUR T's into is sourced from the large vacuum line that originates from manifold vacuum after the throttle.
The Bosch/SAE "Automotive Electric/Electronic Systems" book shows only one type of WUR with enrichment. It runs lean when vacuum is high (idle and steady cruise) and rich when vacuum drops (opening and full throttle). So unless the WUR has been messed-with (as in vent and vacuum points swapped (which is very unlikely)), hook-up the WUR after the throttle.
