I think that it is a great idea. The Trooper 2wd/4wd switch has to do something to tell the TOD computer that it shouldn't engage the clutch pack. If someone with the Trooper book could scan or look at the wiring diagram and let us know what that switch connects to, it would be a start.

We can ignore the part about the vacuum disconnect on the front axle, at least until someone swaps axle housings.
