I have a 1992 Cherokee Laredo bad engine 4.0 litre I have access to a 1993 4.0 litre to swap in. This engine is complete from the head to oil pan will this be a direct bolt in or do I need the wiring harness or the CPU from the 93?
Thanks to all.

Yeah, it should go straight in, but I'd get the harness and CPU as well. Just in case. You never know dude.

Thanks to all who replied I went ahead and bought the 92 cherokee, 4.0 litre auto, I had mentioned that I was going to swap out the engine with a 93 model. When I went to look at and purchase the 92 the lady said it had a ROD KNOCK, I started the XJ it made a slight to moderate clacking noise but stopped after starting. I drove the XJ home Aprox 15 miles no noise whatsoever on acceleration or deceleration. It does blow smoke when sitting for a minute or two. could this just be a bent or cracked push rod? or piston slap?
has anyone encountered this before?
thanks everybody
