Misha,
Your 1997 850 is like our 1998 V70. No car electrics go to the seat air bag, it is just the detonator button that supplies the voltage to explode the bag.

Yes you're right Klausc.
I just surfed over my diagrams and sips airbag info data.
It looks like sips airbag deploys when the sensor is crushed with the door in side impact.
Those wiring and connectors under the seats confused me a bit.It seems that wiring is just for seat belt reminder and heated seats.

Seems like 98's would be worth the wait, unless some very clean earlier SIPS bag seats come available.
My 93 has driver's side power seat, manual for passenger's seat.

Does swapping the side rail accomplish the seat belt adaptation?

I did this on my 1995 850. The only concern is that the rail must be put on "exactly" where the old rail came off. You don't want to have the seat cocked and then jamb when trying to slide it back/forth.
I managed to have both seats at the rearmost positions before swapping the rail with the seatbelt anchor.

Thanks, guys, for detailing this out! Winter in Minneapolis might delay this project for while, but now I have plan.

I don’t think that’s right misha. Robert blew off a sips airbag in a junkyard without any power attached to the best of my recollection, by throwing Magnetti Marcelli throttlebodies at it.

Whoops...already asked and answered , your Honour.

This discussion has generated a lot of interest—555 views, many of which are likely original, some, of course, repeat.

Shows the popularity of Matt's site and also as much as we've fiddled around with our valued rides, there's stuff we still don't know—but it seems like there's always some member who does!

Sips airbags still needs power in order to work just don't use crash data from srs module.
They deploy when side impact happens with correct pressure on their casing,but must be powered.
They do not require power to trigger the seat SIP. I have tested a few at the pull yard with a hammer and they go off just fine.

That takes some balls to do that - its a pretty big bang.
