I have changed the seats in my van (some time ago) and the airbag light has been on ever since. As far as I can see the only connection is/was under the double seat which seems to be connected to the pretensioner on the centre seat seat belt. I can’t find a connector under the drivers seat and as far as I’m aware the seat can’t have had a pretensioner as the seat belt seems to be a conventional inertia reel unit fitted to the B pillar. My question is: having changed the double seat to a single, is there a dummy plug that replaces the pretensioner on the now missing centre seat?
