Don't forget the 2000 is going to have air operated solenoids and electronic controls necessary to engage the 4wd that are a little bit more complicated than just bolting on a bunch of components. Wiring harnesses and tubes etc.

Migiht want to also check wether the ecm has any say in 4wd engagement. I know the system is smart enough not to let you engage it without going slow enough.
