Wow, you guys are making this WAY to hard!!!
This is simple, reach under the passenger seat and UNPLUG the computer to TOD (you will lose ABS but this dosn't affect the braking other than ABS feature) put on manual hubs by super winch ($150 or so). I have done this for well over 6000 miles with no problems. NOTE there is no significant mileage change.
P.S burn outs, doughnuts and power siles are way fun in 2X4
