And you want to be careful thinking ABS will decrease your stopping distance. Some really expensive cars in Europe it does and they advertise that but then everyone started thinking that every ABS system does that and the less expensive its simply preventing wheel skid to allow steering and most times actually increases stopping distance.
My old S10 I learned that they had a wire from the transfer case to the ABS to disable it in 4x4low since your going to be off road in in 4x4low and want the dirt/gravel/etc to pile up in front of a skidding tire so dig in in those situations. I thought about putting a switch in that wire to give myself some control.
New truck (2004) its all controlled via the data bus. So unless you can talk the Intel J8150 protocol your out of luck.
