4x2 to 4x4 cherokee

[kappy]

OK this may be a dumb question but what is involved in swapping a 96 Cherokee to 4wd beside the axle transmission t case yea i get all the mechanical parts. I'm talking wiring wise cause i know that the speed sensor is in the t case how will that end up work? is the wiring harness the same?
thanks guys.

just guessing but i would think on a 2wd the speed sensor would just be located in the tailcone of the tranny, as for wiring i couldnt tell you
