    *Plug N Play* Programming / PATS Security

    For Plug and Play you must have **TWO WORKING KEYS** and follow the below instructions:

    Step 1: Purchase correct ecu for your application - see fitment guide above for details.

    Step 2: Program ecu to your VIN. 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.

    Step 3: Once the ecu is installed you will then need to follow the instructions we include and after completion of these steps the vehicle will be operational - No trip to your dealer! These instructions require no special tools.
