Removing the steering wheel trim
To remove the steering wheel trim, begin by disconnecting the negative terminal on the battery. loosen the 10mm nut and you will be able to remove the terminal. Wrap the terminal in a towel to prevent it from contacting the battery while you are working.
With the battery disconnected, you will need to ‘un-lock’ the airbag. On the back of the steering wheel, there are 2 concealed openings. You can feel them with your finger and if you look at the back of the wheel, you will see a minor divet that will indicate their position. Use a T-25 driver and insert it into the concealed opening (don’t worry, when you remove the driver, the vinyl will close and will conceal the hole). Describing the angle you want to go in at is tough, you will need to figure it out on your own. You will go about 2cm into the opening and feel a spring like resistance. Just push and that side of the airbag will release. Repeat on the other side and you will have un-locked the airbag.
