You have to match the calibration number of the two trucks. If they match then your in business. If you would like, you can get me the Vin of both trucks or the part numbers off the two PCM's and i'll cross them for you!

Unfortunately, it's not as easy as that. Each ECM is flashed to each vehicle. In order for the ecm to work, it would have to have the exact part or calibration number as the original and would have to be re-programed or flashed to your specific vehicle. That would include, but not be limited to VIN # and Mileage.
