Astra H VXR Sprint

With the factory seats removed (they are being replaced with Recaro Pole Position Seats) the side airbags and seatbelt pre-tensioners have also been removed (they are part of seat assembly),and so have the curtain airbags. This puts the airbag light on indicating a fault. This requires suitable resistors to be fitted to turn off the airbag warning light on the instrument panel, which would otherwise be an MOT fail.

To turn off the airbag light the circuits in the seat looms need to be bridged. This can either be done by cutting the relevant wires in the looms behind the seat multi plugs and soldering in resistors, or bridge the relevant terminals in the multi plugs. I decided that in case the car is ever returned to standard with the original seats it would be easier to bridge the terminals in the seat multi plugs as they can then simply be removed and the multi plugs reconnected if needed.

Both front seat multi plugs have had the circuits bridged with resistors (the legs have been shaped to push into the terminals securely) and they are sealed in place with a little RTV (which is easily removable should the need arise):

And then the multi plug is sealed and secured out of the way under the seats:

The same has to be done with the curtain airbag plugs. The airbag plug for the curtain airbags is usually located above the B pillar and quite inaccessible, so to make access easier should there be a problem, the loom with the plug has been brought down to the C pillar at the rear and cable tied securely which makes access easier if required:

And heat shrunk neatly, then hidden out of the way behind the C pillar trim:

And when checked on Tech2 (Vauxhall Diagnostic Equipment) the airbag circuit shows no faults (0 DTCs). Job done and an MOT Pass:
