The Vehicle Identification Number (VIN) is a distinctive code assigned to each automobile, serving as its unique fingerprint. No two vehicles share the same VIN. Comprising 17 characters, the VIN acts as a specific identifier for the vehicle, referencing its unique features, specifications, and manufacturer. This valuable code enables tracking of recalls, registrations, warranty claims, thefts, and insurance coverage. At Clifford Auto Parts, we utilize the VIN to accurately identify the correct module for a specific vehicle.

The VIN (17-digit identification number) can be found engraved at the bottom corner of the driver’s side windshield or inside the driver’s door. Additionally, it can be located on the vehicle’s title, registration, or insurance card.

While entering your billing information during the checkout process, you will come across a text field labeled “VIN” where you can input the vehicle identification number before making the payment. Alternatively, you can email us at, and we will promptly send you a confirmation email to acknowledge the receipt of the VIN.

The computer unit will have an identification sticker with a ‘service number’ indicated. This service number may appear in abbreviated forms such as ‘serv. no.’ or ‘service no.’, etc., followed by the specific identifying number. In most cases, providing your Vehicle Identification Number (VIN) allows us to accurately identify the correct part or service number for your vehicle’s module.

The term ‘Plug & Play’ or ‘Plug ‘N Drive’ refers to control modules that can be installed without requiring additional programming. This typically applies to most units manufactured before 1996 (OBD I). At Clifford Auto Parts, all of our Chrysler, Dodge, Plymouth, and Jeep units are sold as Plug & Play, ensuring a convenient installation process.

This term refers to the programming procedure carried out by our mechanics on specific control modules. During this process, the replacement engine control module for your vehicle is VIN Programmed and flashed with the latest manufacturer updates. These updates are designed to enhance the vehicle’s performance and fuel economy, providing you with an optimized driving experience.
