Before I hose this up, can y'all just let me know if I'm hosed up here?
Connecting the TPS to the MS3, and from what I can figure out the pins and their functions are:
MS26 is providing the 5v reference signal?
MS7 is the sensor ground? (Although the footnotes say "a ground is a ground is a ground"..)
MS22 is the actual TPS measured signal?
I really appreciate y'all's help here; I'm trying to think this stuff through instead of just posting a stupid "walk me through life/spoon-feed me" question.. Thanks for your patience with my screeching ignorance.

Yup.
Yup.
Sadly, the MS 3.0 / 3.57 board does not have discrete grounds for the sensors and logic separate from the high-current stuff like the injector drivers. So in this context, a ground is a ground.

Thanks Joe, I appreciate the help, although I'm a bit disappointed that you didn't include a witty soliloquy about how a ground is a ground unless it's a flammable puppy, including a scholarly dissertation about the combustion point of puppies in various forms of ovens, and so on...
