I just bought a TT RS steering wheel for my B6 S4 which has the 3 spoke NON-multifuction steering wheel. The car has RNS-E. It came with the airbag and harness but no slip ring/clock spring.

I've searched the forums but can't find any info on retrofitting this wheel into a B6, but there are many who have done it on a B7. I'm hoping someone out there has done it and can help me out.

I need to know about retrofitting the 2 stage airbag into the car which came with a single stage and also about the multifunction. I have buddies who are techs at Audi so coding, etc. will not be a problem. I assume I need to modify the dual stage airbag harness and get a slip ring from a car that has multifunction?

If anyone has info on this or links that would help I would really appreciate it!
