This was possible because each of these models received their specific PROM (also known as chip) from the factory. In other words, you can't simply swap a used PCM from one vehicle to the next unless you replace the PROM with the one from your vehicle. When you receive the computer you will need to remove the two bolt cover and swap out the PROM for the one in your computer. No special tools are required to do this. The PROM is what holds the vehicle specific programming. We don't ship a PROM with the computer. If you are in need of a specific PROM please send us a message with the 4 letter PROM you are looking for and I can check our on hand inventory. ******All of our listings are of items that are on are shelves ready to ship.
