Hello, I have a 2010 Ford Explorer Sport Track with 100,000km Long story short, it is at the dealership and needs a new PCM. This is no longer available as a new part and the dealership is having a hard time finding a replacement. I may havw found one, but my question is - does the serial number from the PCM need to be an exact match for a successful replacement? Thanks for your help! serial nu,ber of original is 9L2A1ZA650GG
