Needed an ECM for a 2000 model Ford F-150. There are a few different part numbers so you must be sure to get the correct one. Aftermarket ECM's are rebuilt and no one had in stock locally. I also tried a few salvage yards but could not find the part I needed.
This part was the correct one for the truck I was working on. It had to be programmed, and then the keys programmed as well - it's not plug and play.
