Curious about this AWD thing. From what I understand my 1989 XT6 AWD auto is setup to run 90/10 most of the time, then switch to 60/40 when the front wheels start slipping. So I'm wondering, is there a sensor or wire or *hack* of some kind that I can remove, unplug, cut, rig up so that it runs in 60/40 all the time ?? That's be way kewl !!
