How do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit VIN. You can add it as a note during checkout or reply to your order confirmation email. We cannot ship your part until we have this information.
Is this a new part?
No, this is a high-quality, used ECM that has been carefully removed from a salvaged vehicle. Each unit is inspected and tested before being programmed and shipped to you.
