I found that thread and your post after I posted my message above.
I'm not too surprised about the apparent dead code — all sorts of remnants can get left in "production" code when people are on a tight schedule. Perhaps at one point they thought they needed the flow-control, but realized they didn't (or later fixed something in the cruise module).
Does the ECU talk to the Cruise module (or A/C module) across that serial channel, or is the serial used only by the select monitor (and our laptops)?
How about pin 8? Is that wire populated on any other years/markets?
