I think there was more done than to just turn off the light and loose use of the airbag.. some others have done it.. its gonna take some searching here.. im leaving work and dont have the time to sit and search for you or i would..
as far as the GF... she may leave you after you make her get in and out of those seats on a regular basis.. im glad my GF loved my cars... even the ones with roll / door bars in them... it was fun watching her get in and out..
