Will a pcm from an exact model and year be a plug and play? For instance.....if I remove my pcm of f7lf-12a650-dd code; blx3 and replace it with the same pcm, will it work without reprogramming the original key, and not mess with the pats system? If it does work, do I also need to program or flash it to my vin #, if so, how would I flash my vin to this pcm?
