YES you can use a 99AWD (subframe, suspension, and front differential) with an 02 RWD without wiring or controllers. The JOR 233C 4x4 conversion kit is "manual" operation (with a mechanical shifter) and does not use any electronics or controllers. It is not AWD.. but it is manual 4WD. There is one slight mod to the vehicle that allows automatic shifting (in 4-LOW only)... but is not essential. You can still manually shift between 1-2 gear in 4-LOW without it. None the less, this one wire mod goes to a toggle switch (or switch your rig on transfer case) and is not part of the AWD controller OR the transfer case.
15" 5x5 wheels will interchange with these years too, which is a bonus.
If you wanted a functional factory AWD system.. then you would need the wiring and controllers. Otherwise manual 4x4 is a great option.
