IMPORTANT:
IF YOU DO NOT INCLUDE YOUR VIN NUMBER, THE ECM WILL NOT START THE ENGINE UNTIL IT IS PROGRAMMED.
If you do not include the VIN number when you order, we will try to contact you to ask for the VIN of your vehicle. If we cannot reach you for any reason, we will assume that you or your mechanic will program it, and we will ship the unit without programming the VIN. If the case is that you forgot to do it, and we could not contact you, please send us a message with the VIN through our contact form on this website within 8 hours of ordering. After 8 hours, we cannot guarantee that the ECM is reachable, as it will probably already be shipped.
Make sure that the part number of your car matches any of the compatible part numbers listed here before ordering. If your vehicle is a 2005-2006 Jeep Grand Cherokee 5.7L, with automatic transmission and your ECM has a different part number, please contact us first with the details before ordering so we can assist you and advise if this part is compatible.
