The number 3 coil shorted and burned up the main circuit breaker.  

A shop rewired the number 3 ground wire to the ECM, but yesterday I confirmed the wiring, ensured the positive wire had 12V from the ASD and there was no fire on the #3 plug.   We have an ECM from the junk yard, and I tried writing the VIN, but could not make it work.  Googling around I saw about a SKMM module.  Any advice,

Thanks,
