I have a query regarding the airbag warning light on my st170

I removed the drivers seat which has a airbag in and installed a cobra bucket seat for use on track.

I reinstalled the pretensioner so I could use the seatbelt on the road.

Since fitting the bucket seat the airbag warning light has come on it seems to flash twice several times and then stays on.

Before posting I have read the other posts on similar topics including thins one

I have made a squib following the how to guide and fitted it however the light is still on.

Has anyone got any other advice/ suggestions as to what I can do to turn the light off. I want to be able to turn the warning light off so it will be able to pass future mots once the regs change before I sell the interior

thanks
