OnStar wiring diagram vs. TL

Can anyone tell me whether or not the CL and TL OnStar wiring diagrams are different? I understand that the CL & TL have different head-units and amps which leads me to believe that their OnStar wiring may be different as well. I know I may be reaching with this.

Here is what I'm attempting (using provided diagrams):

I need to identify which wires from the OnStar harness (red or blue) from my 2003 CL w/ Navi are sending a signal. Wires 10 & 11 on Connector A (red) are not getting the job done.

Any help is appreciated.

Thanks!

Let us know how it turns out. I didn't get much help in that thread before it got redirected to a 3rd party product rather then a cheap DIY job.
