Does anyone have a wiring diagram of the wiring for an auto t case for an '86 ranger with the 2.9? Dad's ranger won't go into 4x4. We looked at the t case and found 2 black wires running back to the t case. They have been unplugged from somewhere but we couldn't figure out where.

If someone could post up some pics of an auto t case or even a wiring diagram it'd be so great.

Thanks
