You dont need to worry about the xdrive motor unless you really want to. In my case, I locked the transfer case motor to full 50 50 locked. Obviously only good for off road. If you leave the motor as is, it will function similar to your current transfer case. Just leave the motor installed with nothing plugged in. It does not throw any faults or cause any problems. You could go crazy and try to retrofit the transfer case module, however I havent looked into that. Probably a pain to get working.
