Some notes
If you remove plastic panel under steering wheel don't forget to unplug parking brake switch.
if you pull to hard on this plastic peace the hood latch rubber grommet will pull out of fire wall don't forget to push this back in.
Also GM provided fuse box with no bolts under steering wheel forget the bolts and save your self time remove the threaded silver clips and just put zip ties threw the existing holes it will save you a lot of grief and you possibly might not have to remove any plastic.

I just bought a 2022 Silverado 2500. My auxiliary switch has no wire hooked to it. I’m assuming I have to order the wiring harness?

Yes more then likely
