86 cj7 258 inline to a automatic 4.0.

In search of as much information on changing my 86 cj7 258 inline automatic to a 4.0 in line motor fuel injected. Need all the technical information involved installing this newer motor. I understand that this is a common change over. Information greatly appreciated. Thanks James

You'll need the wiring harness, the ecm, the sensors, tcm from the donor vehicle.
I've never dine this particular swap. Most of my experience is with the Cherokees.
