[urq] air con wiring and wheel arches

[spot.ontheroad]

Here's two un-connected questions for you.
Where can I find a wiring diagram for the air conditioning on an Audi Coupe quattro 20v (7A engine) (the smooth shape that came after the ur-q?

And secondly does anyone know when one might find a set of the bolt-on wheel arch extensions as on the A1 Rally cars?

Any pointers gratefully received
Many thanks
