I've taken the door panel off, personally, I can add some input. Could be yes, could be no. Could be yes because mine came without the pigtail for the wired keypad in the door harness. Could be no because I disconnected that switch panel and I believe it's just one, maybe two plugs, from what I recall. I believe it's a standard connection. Same pins/wires/pinouts.
I am thinking what they do is have those wires there for the door switch panel, they're all the same. Then the truck either comes with the folding mirrors and folding mirror switch. Or it doesn't and the plug is still the same. Then as you mentioned, probably module programming.
Either way, OP got hosed. Having power folding mirrors makes no sense without the switch, even if you can set the autofold to on. I'm thinking the truck is already programmed for it because he can use the autofold feature. Some doofus on the line grabbed the wrong panel.
OP, worse comes to worst, look up my posts on here about the SecuriCode keypad. I shared videos on how to take the panel off. If you can get them to cover the proper switch panel, a DIY install is easy. I've taken that switch panel out and unplugged it before. It's worth the 15 min to see if the proper switch panel is plug and play.
