For Plug and Play you must follow the below three steps:

Step 1: Match your part number series per above fitment guide

Step 2: Match your ecu security. Most NGC style ecu's have SKIM security and are not plug and play. (You generally will have grey ignition keys or chipped keys.) 

Step 3: Program ecu to your VIN and mileage. We provide free programming for our customers. During checkout you must list your VIN and mileage in the "Notes to Seller" for us to program the ECM. If we do not hear from you through the order notes or an email we will assume your mechanic is performing the programming (no problem at all) and we will ship the ECM out promptly.

• Mounting points are all open and intact
• Pins perfect, none are broken or bent
• *WARNING** Unit has chipped connector plastic and one lock tab is missing. We are including a large zip tie so you can tighten that connector in place. Review pictures and do not purchase if you are uncomfortable with this.

This ECM comes with a 90 day warranty from the date of purchase. Please keep a copy of your purchase record which we will send with your item.

If you would like to return your core for a $35 partial refund let us know during checkout through the "notes to seller" and we will send a prepaid return label with your order. It's that simple. Once your original item comes in we will process your refund promptly.
