Programming / PATS Security
For Plug and Play you must do the following three steps:
Step 1: Match your part number per above fitment/interchange notes
Step 2: Program the ecu to your VIN. You will need your local mechanic, Ford dealer or properly equipped Locksmith to program your VIN into the ecu. Without 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 your vehicle does not have PATS then after the VIN is programmed the ecu will be plug and play.
- Pins perfect, none are broken or bent
- Mounting points good
