Programming / Security

For Plug and Play you must do the following three steps:

Step 1: Match your part number per above fitment/interchange notes

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.
