Programming

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 a message through eBay we will assume your mechanic is performing the programming (no problem at all) and we will ship the ECM out the next business day as directed by eBay.
