COS3 pin 56 question

[JUSTASBC]

I have COS3 with pin 56 being used for 2 step launch control. My problem is, my OS (in my sig) offers a flex fuel version that was in the 2005 L59 Silverado. I really want to run the flex fuel and the 2 step. What options do I have?

It looks like I was looking at the wrong plug. Pin 56 of the blue plug is for the fuel composition sensor, and pin 56 of the green/red plug is for the valet mode. I should be all set. Thanks to everyone that looked though.
