Airbag OFF
Airbag ON
I'm waiting on my OBD2 to USB cable so I can reset the airbag light. It should be here sometime early next week. I can also rig it up with an LED that runs off a battery; it will only be illuminated when the airbag is off (to save power). I bought some Velcro backing so I can install the switch anywhere in the cabin.
