Programming / PATS Security
For the ecu to work properly you must do the following three steps:
Step 1: Match your part number per above fitment/interchange notes
Step 2: Program ecu to your VIN. You will need your local mechanic, Ford dealer or properly equipped locksmith to program your VIN into the ecu. Without doing this you will get a "no start" condition.
Step 3: If your vehicle has PATS security (Most Ford/Lincoln/Mercury's do) you must have your keys programmed. We recommend you have this done by your local locksmith. In most cases they will travel to your location and the process takes less than 30 minutes. No towing necessary and your local locksmith will be cheaper than a dealer. If your vehicle has PATS and is not programmed you will get a "no start". If you do not have PATS after programming your VIN into the unit it will be plug and play.
- Pins perfect, none are broken or bent
- Mounting points good
