    Well the 05 3.7 is already half installed into the 03 body. I know the intake needs to be swapped back to the original 03 but the oil pan, motor mounts,cans ac stuff seems to be the same. Does the reluctor and crankshaft sensor absolutely have to be swapped or could I possibly swap the computer as I have the entire 05 vehicle

    So ur telling me the only way to make this 05 engine fire in the 03 body is to pull it back out and pull the crank out??? What a bust this is turning out to be. You really think swapping the computer is not a viable option? Is it just the reluctor that needs to be changed or is there anything else definitively that I'm looking at???

    I am by no means an expert on the 3.7 gassers but there are major differences in the wiring harnesses between the various year KJs so I doubt swapping over the PCM will work.

    Obviously if all wiring was swapped over as well as all electronic modules such as PCM, TCM, BCM, ABS components etc. then you basically have a metal shell with all the 2005 components inside it and it should work.
    This sounds like a lot of work to me.

    All other KJ Forums that I have visited over the years have basically stated that the reluctor ring has to be replaced!
