You can see the pics for a mostly step-by step account. One article that I found helpful was this post on removing the center console.
See the pics here.
You could also do this with the Proclip, but it looks to me like it expects to go in the bottom button location (?), and I already have a Mikado garage door opener button in that, so....
One nice thing about this, is that to "remove" the install, I only need to buy a new "blank" button (~$2, I have it on order already), remove the one I have, and pull my power cable. No holes in any permanent part of the car.
