After helping install this earlier in the week on someone else's car, I thought to myself I want this on mine. This being "Comfort indicators"
There are a few different kits out there. You have the VW one designed for OEM fitting or after market one:
eBay Adapter-Universal
Its says it fits Audi A3 8L facelift but it does also work on the Pre facelift. I managed to pick my set up from Leigh on here.
I'm no electrician and it only took about an hour to do, including taking the Head unit out and fitting it all back in.
So all i got was this:
I found it easier to whip put the head unit, the top surround, cup holder and the blank buttons for better access.
Unplug the hazard switch and remove
The Adapter-Universal relay came with instructions in German. Leigh kindly translated it for me as:
OEM wire colour / what the wire is / [universal kit wire colour]
Red wire: Terminal 15 ignition [wire black]
Yellow wire: left light switch [wire black/white]
White wire:Terminal 49a [wire black, white and green]
Blue wire: Right warning light [wire black and green]
Black wire: Terminal 31 ground
Like me you probably thought all those wires don't match up with what I have. Your right, in my 1997-8 A3 AGU my hazard switch has 6 wires, and only 3 of them matched the guide where as the Facelift A3/S3 has only 5.
[Pin location] OEM wire colour = [universal kit wire colour] - My guide
Splice and taper
[Pin 7] Red & Green wire = Red wire
[Pin 3] Black & white wire = Yellow wire
[Pin 5] Brown wire = Black wire
[Pin 2] Black & Green wire = Blue wire
[Pin 1] White, black & Green wire = White
Electrical tape to seal and fit everything back in
