The PCM has protection against some things like that. How extensive it is I don't know.

Worst case scenario, get the dealer to replace all the harnesses and if it does turn out the PCM is screwed and they won't replace it (although they should since it'd be collateral damage from the wiring harnesses), get one from a wrecking yard for $50.
