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 guide

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: 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.

Item Condition

  • Mounting points are all open and intact
  • Pins perfect, none are broken or bent
  • Lock tabs in place
  • Connector plastic may have minor chip but pins, guides and lock tabs are in place.

Warranty / Core

This ECM comes with a 90 day warranty from the date of purchase. Please keep a copy of your purchase record which we will send with your item. We'll send a prepaid return label for your core. Once your core comes back we'll issue a $50 partial refund through eBay.
