Does anyone know what wire it is that causes the airbag light to turn on when bumped?

 

You're talking about the air bag that's built into the seats right? I would check the connectors under the seat, maybe it wasn't plugged in properly at some point and came unplugged now... That would be my first place to check.

 

Yeah it is one of the wires under the seat, just not sure which on:/

 

The wire under the passenger seat has been found to be stretched tight and pulling loose from the connector.
