This is a used engine computer removed from a 1997 Ram 2500 Cummins diesel truck. The Mopar part number from the last authorized software update is shown as 56040504AC. This was removed from a running truck.
This will fit 1997 Ram 2500 or 3500 models with a 5.9L Cummins engine, Federal emissions and an automatic transmission. If you are not sure whether your truck has California or Federal emissions, please message me with your VIN and I will try to help you determine.
Reprogramming or Reflashing at a Ram dealer may be required in order to program your VIN into this computer. Check engine lights may be present if the computer is installed without reprogramming.
