changing the steering wheel for a non-airbag unit is easy.
1. Quit the airbag fuse. A 10 min wait is recommended (airbags are designed to ignite at low voltage)
2. Lock the steering wheel at 90º and use a screwdriver or similar with the two metal locks on the back of steering wheel.
3. Extract the airbag, disconnecting the 3 contact cables : 2 for airbag, 1 for horn
4. Now you can quit the steering wheel using the T40 torx, and put the new hub and steering wheel (momo rules!)
5. Place a 2.5 ohm resistor in each airbag cable. This makes the cPU think airbag is OK. Otherwise, ALL airbags and pretensioners refuse to co-operate
6. Remember to return the airbag fuse !
7. Be careful with the removed airbag. Its a charged bomb !
