Frequently Asked Questions
Do I need to get this ECM programmed by a dealer?
No. The main benefit of our service is that we program the module to your vehicle’s specific VIN before we ship it. This makes the installation process much simpler, saving you time and the high cost of dealership programming.
How do I provide my VIN number?
After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN. We will provide clear instructions on how to do this. We cannot ship your part until we receive the VIN, as the programming is essential.
My old ECM has a different part number. Will this still work?
Yes. This ECM, part number 12606127, directly replaces several other part numbers like 19260753, 12588335, and 12606126. Please check the fitment list in our description to confirm it matches your vehicle’s make, model, and year.
What is a ‘classic style’ truck?
For the 2007 model year, GM produced both the old body style (called ‘Classic’) and the new body style. The ‘Classic’ style has a distinct crease in the outer door skin, matching the 2006 models. This 2006-2007 Silverado 3500 ECM fits the ‘Classic’ 2007 models.
Is any additional setup required after installation?
In some cases, a security relearn procedure may be required after installation. This is a simple process that can typically be done without special tools and involves a sequence of key turns. We can provide instructions for this procedure if needed.
