    Common problem on some swaps for whatever reason Have your tuner delete the code.

    Not sure. I believe they are activated by the PCM. Hopefully your new PCM was flashed to have the proper pinouts activated to work the fans. Then it's just a question of tracing the wires and hooking them into the PCM.

    The new pcm will control you fans.

    The fan harness is part of the headlight harness actually, so it should function just like stock.
