Wow, read the entire thread to make sure I didn't miss something.
Here's what I think. Install a switch, as others have suggested, to turn off the transfer case, one wire, probably a 12volt lead. Then the TC will get signals but will not be able to engage. The car will be a 2wd car with all the other traction control stuff working. Turn off the DTC, as we all know how to do. Voila!
All that pulling fuses talk is like turning off the main breaker of your house to turn off the tv.
