I'm sorry I don't have the specific part number on this ECM. I did attach a picture of the VIN. I believe this has been remanned very recently this truck had some pretty severe oil leaks, so it does look a little dirty, but compared to the rest of the engine bay it shined like a diamond.. This was a running and driving truck, I drove it home a few weeks ago. 2005 Ram 3500 5.9 Cummins 4x4 NV5600.
