Yes, exactly, by disconnecting the wires either under the car, or inside, you turn off the transfer case (making the car RWD with no ABS). I don't know where the module exactly is, since I didn't disconnect it that way. The service manual here:
https://www.newtis.info/tisv2/a/en/ would help with removing trim...that'll be an interesting way to do it if you choose to do so. According to your picture, it looks like it's behind the luggage compartment trim, so you gotta remove some trim pieces to get to it. I'd suggest just unplugging from under the car. It takes only a minute. As for the video I linked you, I'm talking about the 2 wires from 3:56-4:13. Loosen the heat shield by removing the one 10mm hex, and pull it down. Then with a pick, disconnect the 2 plugs (they're snap-tabs). DO NOT UNBOLT any parts of the transfer case crossmember (the big black bar). It is kind of a tight space to work with and it will be in the way, but with patience, it's pretty easy once you do it.
Edit: here's the inside location:
