Help id B5 airbag wires

[HUFset]

I need to id the wires on a B5 and 8V airbag.

B5:
Blue - Airbag 1?
Brown - Airbag 2?
Purple - horn?
Green - horn ground?

I don't want to explode the airbag after re-pinning the harness.

Blue is definitely airbag and brown is definitely airbag ground. I'm not sure about purple/green though.

Thanks melo. I'm trying to retrofit an 8V airbag on an S3 wheel. This is how I have it wired now.
B5 8V
Horn | purple | blue
Horn ground | green | brown
Airbag | blue | green
Airbag ground | brown | black

Where'd you get the S3 wheel if you don't mind me asking? I really want to get my hands on one. I've been struggling to find another one at a decent price after I watched one slip away in the 8V classifieds.

Right hurr.

Um, no. That's where I got the idea.

Okay.

[HUFset]

Okay.

Thanks for your contribution. When I figure it out, I will post a short diy. I think I'm close.

Can't wait for the guide. However can you use the passat b5.5 airbag harness? It looks more plug and play

I think they are the same connector. I've looked through passatworld for some sort of DIY but I think their airbags are different because of 4 spoke wheel design and multifunction buttons. It depends on the clock/slipring terminals. I just don't know which wires are airbag 1/2 on 8V single stage airbag. I'm fairly certain I know the B5 A4 airbag1/2 and horn/ground from previous DIYs on AZ and Vortex.

The pic is incorrect, I had the horn wires pinned backwards in the B5 harness. I successfully installed my 2013 SLine A3 FBMFSW with 8V single stage airbag into my B5 A4 this weekend. The following pic is the schematic for a re-pinned and WORKING B5 airbag harness with 8V airbag wires.
