There is a lot of information out there for how to install a new steering wheel in the C6 and add steering wheel controls. However, a lot of this info is scattered around and geared towards factory radios. I decided to make a full video of installing a Centennial Steering Wheel, new clockspring, and a Maestro SW control box into 2006 C6 equipped with standard wheel and aftermarket Kenwood radio. Hope this helps! Link below:

 

Excellent job
I too just installed the upgraded clock spring to go with my new steering wheel. I haven't purchased the stereo yet as my car is down for additional repairs and upgrades, but I agree the various DIY threads were scattered all over the place.

 

A bit late with the thanks, but THANKS.
