[s-cars] Passenger Air Bag 1992 retrofit?

[Iler, Denis]

Hello S-List,
 
I have been a lurker for some time now and really enjoy the assistance
available for do-it-yourselfers, like me. My 1992 has been a great car
with a minimum of difficulties. What I have not noticed is an effort to
fit a passenger side airbag into a 1992 UrS4. According to Bentley the
1994, have the pass. bag, as well as the locking seat belt retractors.
It would seem that installing the airbag and later electrical harness
would be preferable to moving all of the RS2, FMIC and suspension bits
to a later model already so equipped. Wrong?
 
Thanks for any and all help, Denis in CO
