16V Scirocco wiring guru needed...

[drew at scirocco.cs.uoguelph.ca (Drew MacPherson)]

IIRC the system is intended to operate as follows:

low temp circuit on thermo-switch in rad activates the low speed on
cooling fan via the relay.

turning on the AC activates the low-speed on cooling fan via the relay.

high temp circuit on thermo-switch in rad activates the high speed on 
cooling fan via dirct-wire.

some cars (A2's I know for sure, don't know about Sciroccos though) had 
after-run circuits which would activate the low speed fan (via the relay 
and a control unit in the dash) when engine coolant temps hit some level 
(105C to 110C) with the ignition off.

HTH,

Drew
