Wiring diagram for EATC?

I'm trying to figure out what sensors I need to run the EATC in my Lightning. I have a donor wiring harness (I think it's from a '99 Expedition), and I'm trying to trace all of the wires from the EATC connectors to see where they go, but I don't want to mistakenly remove the wrong connector.

Does anyone have a wiring diagram that would show electrically what goes where?

Thanks, but that looks like the regular AC, with the manual seletcor *****. Do you have one that shows the EATC? It'd be from either an Expedition or a Navigator.

Thanks again!
