Transbrake/launch control button

I am wanting to put a button on my steering wheel to control the launch Rev limiter on my Sniper EFI. My Dart is a full interior streetcar that sees the track a few times a year. I have a factory Tuff wheel in my car and I would prefer not to damage it by drilling holes. It's looking like that is the only sure solution.

Do you guys have any tips or tricks on how to mount one up?
