Hi, will a late model 2012 l322 steering wheel fit to an earlier car (2005) and will my old airbag and all controls work? Thanks

Positive there's a thread here somewhere , you need to swap one of the electrical connectors over from inside the old wheel, no cutting necessary, hardest part is disconnecting the front of the wheel to access the retaining nut, took me ages.
If you contact Craig cam tech he usually has some in stock!

thank you Mr T

Certainly do sir
