Do you have a C6 or C5?
I have been looking at this for my C5Z. After studying the manual, it appears that there are 3 potentiometers ganged together as input to the PCM from the foot pedal. I had hoped it was just one, but I guess they needed redundancy for safety. Unfortunately, the 3 pots have different values and go in different directions with increasing throttle.
I have never been able to heel toe shift, so I planned to use a Hurst shifter ball with integral momentary switch as the actuator. Unfortunately, once I discovered the complexity, I have not been back to look at it. I would buy such a kit if it were available.
