You need to remove the airbag. To be safe remove the - pole from your battery first so the power is completly off.
Then remove the airbag like this video:
Look at it carefully a couple of times. It took me a while more time the it took the guy in the video. Just take it easy and don apply any brute force.
You need a new connector cable part number 32306854768 to connect the controls.
The existing small little cable with white connectors for the horn will have to be removed, and not to be used anymore. The horn will be connected through the new cable instead.
There are two screws from the back of the wheel to release the inserts. After they are released just fit the new controls and put back the screws.
Here are another set of pictures I found to explain how you remove the controls.

Sorry if I didn't explain it very well, feel free to ask more questions.
