Install Notes

• Disconnect the negative terminal of the battery. Make sure the battery connector is not touching the battery post.
• Disconnect and remove the module to be replaced.
• Install and connect the replacement module.
• Connect the negative terminal of the battery.
• See "Programming / PATS Security" below for additional install instructions. 

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 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".
