Open your hood and look at the battery, Now look at the bottom left side of the battery and you will see a black plastic box mounted just below the battery. The PCM / Powertran control module is in that box.

That is it? thought they would have it in the cabin, not somewhere it can get exposed to the elements.

Thanks,
