The TC is a 2008 'spec'. Thanks for the info.

Even more than wave form - We are talking about an encoded message within a stream of pulses. I actually have an enhanced version of my cruise control indicator module that I developed, which can drive separate LEDs for ON and SET. I haven't offered it for sale as of yet, as it is a $50 device, as opposed to the $25 one that just handles reading "ON" via the feed between the switch and the ECM. Set is more complex, as you really need the message feedback from the ECM to know that all conditions were met to allow the ECM to set it.
