Engine swap, now no 4x4

[speedy_fisher3]

I just swaped my 4.0 and put it a 4.0 out of a wreck and now my four wheel drive will not work. The light will not come on when I push the button. I did put front brake pads on after the engine swap was complete. Have I unplugged something or could it be that I don't have the auto hubs right. Oh BTW I left the tranny in and only pulled the engine so I shouldn't have anything unplugged but who knows.

Thanks
Speedy
