Yep, just unplug the MP unit and plug the stock one in. I always
disconnect the negative battery cable whenever I swap out PCMs. There
are probably 3 connectors, make sure to get them plugged in the right
order. (I don't remember if they are keyed or not, but I don't think
they are, in which case it would be physically possible to plug it in
wrong.) Usually one connector is black, one is grey and the third is
white, and there will be a corresponding sticker or something on the
computer to indicate which plug goes where. If there isn't such a
sticker or other indicator on either PCM, you may want to just use a
pencil or a sharpie to write the colors below each receptacle for
future reference.
