    I am swapping my 4.2L carburetor engine for a 4.0L fuel injectioned engine. What do I need to do ?

    Welcome to the site! I cant help with this, but Im guessing you would need the ECU, and many of the sensors.

    The easiest would be to get the whole wiring harness, front to back.
    Are you going to keep your current transmission or swap in the entire drivetrain from the donor vehicle?

    Prerunner1982. I am keeping the old transmission. It was swapped out with new one. Less than 10,000 miles ago.
