Default Trouble disabling airbag warning light

https://www.scoobynet.com/attachment...1&d=1511729481

Car is 1998 import Version 4 STi
Original steering wheel in place, presumably still contains airbag.

I have my MOT tomorrow, and followed some posts I had found concerning my Airbag light, which will not go out.

I bought 3 3.3 Ohm resistors. I disconnected the battery. I cut the cable I believe comes from the airbag in the steering wheel just above the yellow joiner pictured above. I soldered a 3.3 ohm resistor from Maplins (receipt says M3R3, Min Res 3.3R) across the 2 wires. I used shrink wrap, the job looked better than the main item in the picture (the black bit is my original try that I cut off when it failed). I reconnected the battery. I started the engine. Disappointingly, the Airbag red light did not go out.

I repeated in case the soldering was the problem, but the effort shown in the pic does not work either.

Did I cut the wrong cable? Did I use the wrong resistor? I did read one post recommending 2.2 Ohms, but the others recommended 3.3 so I went with that.

For now I have removed the Airbag bulb from the dash, but I doubt the MOT people will accept that.

Please let me know if you know what I can do to fix it.
Thanks, Tom

By some kind of miracle I did pass the MOT, which was a great result.
However, I really would like to know the answer so that next year I don't have to worry.

Anybody had success doing this another way or using a different resistor?

I thought it was a 2.2 ohm resistor ?
