Just to be clear, you are looking to find out other vehicles that share this ECM so that you can use one out of another vehicle?
I attached the part numbers below as well as the process to reprogram the ECM. Unfortunately I don't think you are going to be able to use one out of another vehicle as they are programmed to your VIN and the theft system is going to prohibit you from starting the vehicle.
Plus even if it did work, you will need to find a vehicle that is equipped the same as yours because if the vehicle you removed it from was different then it will not operate your vehicle correctly.
Let me know if I understand this correctly. If not, please correct me. Thanks
