First, you need to either disconnect the battery or pull the horn fuse
Tools you will need:
Flathead and Phillips screw driver
Torx driver (Don't know the size)
Once the battery or fuse is disconnected, on the left and right backside of the steering wheel, you will see a rectangular tab. Use the flathead to pull it out and expose the torx screw.
Unscrew the torx screws and pull out the air bag. you will then see the two screws that hold the steering wheel contols.
Unscrew those, disconnect the wiring, and you'll be set
