Thanks for the pics! Turns out those plugs only work for side airbags, and won't fit the ones on my car.
Female plug
Male plug
Anyways, tonight i unplugged the sensor on the passenger seat and then sat on it. The warning light on the centre console obviously didn't turn on. Also, the airbag light on the dash was on for 6 secs and then turned off which is normal, and means airbags will still work.
From this scenario, it looks like as though having the weight sensor unplugged on passenger side the driver's side airbag would still deploy, but my question is will it deploy the passengers airbag if an accident was to incur?
