It should be m8, the wiring plug on the airbag may be different from the one in your car!
3 options on that:
1. Dont connect up the airbag, just the horn [will leave airbag light constantly on in dashboard panel or/and take out bulb for said, mega pain]
2. Get a 3 ohm resistor and connect it too the supply wires from the car loom connectors only bridge connections but NOT ON AIRBAG
3. Cut the two supply wires from the airbag, one at a time with the battery disconnected, rejoin same to new bag.
I MUST warn you that anyone that carries out this does so at their own risk!!!
An airbag is EXPLOSIVE
