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

Step 2: Update and 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. **ECU is not plug and play without programming**

*** If for any reason you believe your vehicle has Ford PATS Security please email us prior to purchase. ***

• Mounting points are all open and intact
