I'm pretty sure coup will work for sedan and I'll verify once I get mine. As far as the passenger airbag issue, https://airbag360.com/infiniti-g37-g...pass-661-p.asp is a product that will fix this supposedly (which i'll also verify after installing when my seats come)

 

Everything worked out well but I'm still trying to figure out the dash airbag light. The passenger airbag off is no longer on so I believe the airbag works and it's a sensor/ something I have to reset.

Never replaced my seats, just removed them for cleaning... but this took care of airbag light when I put the seat back in the car.

 

I've tried that a dozen times and it still comes back. At this point I'm just disconnecting the battery for a bit to see if this will fix it. The passenger airbag is on which is all I really care about so if I can't figure this out I'll probably just leave it tbh. Can't be bothered taking it to Infiniti and paying way too much for them to help. We'll see if this works or not.
