Frequently Asked Questions
Is this ECM really “Plug & Play”?
Yes, absolutely. We pre-program the module using the VIN you provide during checkout. This ensures it’s fully configured for your specific vehicle’s options and security system. All you need to do is disconnect the battery, swap the old module with this new one, and reconnect the battery. No further steps are needed.
What information do you need from me?
We require your vehicle’s 17-digit Vehicle Identification Number (VIN) and current mileage to program the computer correctly. You can typically find your VIN on the driver’s side dashboard (visible through the windshield) or on your vehicle’s registration and insurance documents.
