E53 steering wheel conversion to E46 SMG M3 Paddle shift wheel--Instructions and pics ( 1 2)

On a 2002 the bottom trim can be removed without removing the airbag by just removing the two screws. If you can see the entire trim as pictured, all you have to do is remove the two screws and pull it out. It presses in at the top so you will have to apply some effort. If the indentation at the top of the trim is not visible you will have to remove the airbag. If so, the key is the angle to be able to release the spring retainers that hold it in and you MUST remove the negative battery terminal before releasing the airbag and press it back into place BEFORE you reconnect the terminal. If you have a picture steering wheel with the current trim installed I can tell you for sure what you need to do.

The above thread may be helpful to you.
