    You can use the 99-02 harness to run a 03+ PCM, a few wires have to be swapped and the TAC wired in.
    You won't be able to use drive by cable with the green PCM. You would then have to run 03+TAC and TB. Also the PCM controlled HVAC is triggered by serial data.
    All of that would end up costing you more than the PCM.
    Just stick with the 0411

    YOu can use the blue/green connector pcm on drive by cable vehicles. The express vans use drive by cable and they use the blue green connectors.
