Frequently Asked Questions
What do I need to do after I place my order?
After you complete your purchase, you must provide us with your vehicle’s 17-digit VIN (Vehicle Identification Number). We use this to program the module with the correct software and settings for your specific truck, ensuring a perfect match.
Is this difficult to install?
For most DIYers with basic tools, this is a straightforward installation. The module is typically located in the engine bay. The process involves disconnecting the battery, unplugging the electrical connectors from the old module, unbolting it, and then installing the new one in the reverse order. Since it’s pre-programmed, no further steps are needed.
Will this computer require any additional programming after installation?
No. This ECM comes fully programmed to your VIN and is ready for installation. In some GM vehicles, a security or anti-theft relearn procedure may be required, which can typically be done without special tools and instructions can be easily found online for your specific model.
How do I find my vehicle’s VIN?
Your VIN can be found on a metal plate on the driver’s side dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
My original part has a different number. Will this still work?
Yes. This module is a direct replacement for multiple part numbers, including 12625455 and 12629009. As long as your vehicle’s year, make, and model are on the compatibility list, this module will function correctly once programmed to your VIN.
