I have been to this forum before, and found answers to my questions, however, this question does not have a definitive answer. I have my 98 4.0 OHV with a cracked head, and also a scorched #6 piston. I found a donor 2000 4.0 OHV that can be used as my replacement, and it has far less miles. Is the PCM and wiring harness the same? Will I need a 2000 harness and ECU/PCM to with the donor engine? Even after my research from both the online sources and the Chilton's manuals, I am still uncertain. Any feedback would be greatly appreciated!
 






take all the wiring, sensors fuel rails and injectors off the 98 motor and put it on the 00 and you should be good to go.
 












it is. the fuel system is different between the 2 years (98 is return, 00 is returnless) as well as the wiring is a little different as well (some connectors are pinned different, or the connector ends are different)
