So after about 3 hours of searching online and in manuals and crawling under the truck, I found the pcm...right under the hood, on the firewall on the passenger side:


Now, after I located it and took it out, i looked online for a while searching for the correct pcm, one with the correct hardware codes:






Now, I'm assuming that my pcm is the Ford original one, but I wonder if the number cast into the housing is supposed to match my trucks VIN, because it does not. The one I'm buying says it needs the VIN, and I'll have to get new keys made, but it comes preprogrammed and flashed....should I trust it? Would I be able to install it myself or should I have Ford do it? I've already figured out how to do it on my own and it's a 5 minute job to do, and the only reason I was originally going to take it to Ford was for them to program it and since they dont need to my thinking is for me to install it myself then have the truck towed there or push start it and have them do the keys. Any suggestions, input, or ideas is appreciated.

Yes it does, the only thing I should need after the pcm is installed is 2 new keys programmed, at least that's how the dealership explained it to me.

Mobile locksmith? Might be cheaper than putting it on the hook.

Would disconnecting the battery be the only thing I should have to do when replacing the computer? Or are there other steps...?

I would disconnect the battery and wait 10 minutes or so. Don't over think it pal they are way tougher than a motherboard! It will be fine.

It's just been brought to my attention that my PATS issue could be in my instrument cluster and not the PCM. How would I be able to tell which one is causing the problem? Mr. Technician at Ford said they swapped some relays and replaced one and said it worked and then stopped working again, so they came to the conclusion that it was the PCM that was bad. Even though it's a little late that I ask this since I've already ordered the PCM, but hopefully I could return it if its not the PCM.
