Just in case anyone didn't know. If you want to fix your passenger seat occupancy sensor causing airbag light on dash, there is no need to cut the blue and white wires on pins 2 and 3 at the brown plug.
Simply find the little black 2-wire plug, unplug, and plug your resistor straight into it. Or if you really want, remove the two pins and solder the resistor to them. That way if you ever want to go back to a seat pad you retain the oem look without any patched up wires.
The little plug is also a lot easier to reach and remove than the same wires at the big brown plug.
