Ok, I didn't know about that site: but it sure would have been easier if I would have had a roadmap instead of "reverse engineering". Not sure I need it now-- I'm basically finished with what I intended to do; but I'll sure look into it. I guess my strategy was--I have a perfectly functioning brand new truck and I don't want to mess up anything, so I'll just add on. That said, as of today, I have working heated/vented seats, power passenger seat, and it appears the heated wheel will work as soon as I receive and install the clock spring. I'm also prewired for an inverter, and Memory function if I decide to implement it in the future.
