Frequently Asked Questions
How do I provide my VIN?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive this information, as the programming is essential for the part to function in your vehicle.
Is this a true plug-and-play part?
Yes. Because we program the PCM to your VIN before shipping, it is ready for installation upon arrival. In most cases, you will not need to perform any additional programming.

Instructions can easily be found online for your specific model.
