Did I fry my PCM?

As I was installing new crank sensor wires, one of the wires touch the positive side of the battery and there were some sparks and smoke.
the PCM was connected to. what are the chances that I fried the PCM??

I'd think the PCM would be protected by one of the fuses, and that would open first.
