Jerryd,
If you PM your email address I'll send the wiring diagrams.
On a petrol S3 2.25 & 2.6
Spade 1 has the brown wire connected (should be two brown wires together).
Spade 2 has a white wire connected.
Spade 3 has a white wire with a red tracer (stripe).
Spade 4 isn't used. On a diesel this is connected to the glowplug circuit.
Hope this helps.
Regards,
Colin
