Hi
Try the search key on here.
There are tons of info on this topic.
The BIG letters and numbers on the eec are the program code.
Junkyards are a good source.
What is yours bad?
If it melted/leaking capacitors, they can be replaced by anyone with a spiffy soldering iron in under 10 minutes.

That number you listed is a Ford part number for the PCM. The last part "CC" is what determines the calibration of the programming inside the box. Your part of F2TF-12A650-CC is designed to work on a F-series truck with a 5.8L engine/E4OD transmission with Federal emissions.
At the time these trucks were produced there were several variations of calibrations for the PCM. The main differences would be Federal/California/High Altitude emissions as well as different engine/transmission combinations.
NAPA carries Standard Motor products rebuilt PCMs. Their part number for a direct replacement is EM885. The price I see online is approx. $175 USD. The core charge is $78.
Before spending that kind of $$$, let us know what issue you are trying to resolve.

I wrote this reply in another post.
I do not know if this will help you, but my truck idle's at around 2000 rpms. When I got it the seller said that was normal, bull----. I replaced ever sensor, upper intake gasket, vaccuum hoses, check codes and it stills does it. I have been all over the internet and find people with the same problem but no answers. What I discovered about a month after I got it, if I hit the gas (rev the motor for a brief second) right when the motor starts running, the idle goes down to normal about 98% of the time. If it still idle's high I just repeat the above step. I been doing this for 2 years and 15,000 miles. I think mine is the computer, but I am to cheap to replace it. I figure I just keep driven it until it breaks down. It cound also be one of the new sensors I replaced was bad when I got them.(autozone brand)

It's not likely the computer is going to fix your problem. Start with the basics first. Check for codes. Warm up the engine and transmission then follow this: Ford Fuel Injection » How To Run a Self-Test or purchase one of these Equus 3145. Your truck should display 3 digit codes. Use this to decipher your codes: Ford Fuel Injection » 3 Digit Self-test Codes 111-171
We can help you with the codes if you need it. The most common cause of a high idle is a bad TPS, sticking throttle cable or IAC and vacuum leaks. Any and all of the plastic vacuum lines and metal reservoirs are suspect before proven innocent.

We had some kind of vacuum tester, prob got borrowed but you should be able to pull a vac line and literally suck on it and see if it holds your tongue for a few seconds at least.
My vac lines are patched in about 3 different places with see thru fuel line and for some reason they don't collapse and no clamps necessary.
I think there was also somethng about cleaning the idle valve area since a new one will still have to deal with the crud plugging something or other and may not change anything with a new one.
