How dangerous is it to work near airbag cables?
I don't want to have one ignited in my hands
The codes for the boxes are the same for left-wheel car, I suppose, aren't they?
As long as you disconect the battery and wait at least 10 minutes you will be safe with the airbags.
I did mine without unplugging the airbags - there is enough wire to tilt the seat up enough to fit the boxes. The holes are all pre drilled so you are only inserting 4 screws.
I would guess that left and right hand drive seats are the same so the boxes will be the same
