How hard is it to switch out the PCM. Is it just a simple switch the new one with the old one. Or is there more to it. Im thinkin bout gettin one and i just wanna now what ill be gettin myself into

Not for sure being as I'm still stock but I would guess its as easy as unplug and plug in...dunno though

there are 2 connectors that screw to the pcm.

sounds like a pretty easy project...good luck
