EEC module?
I am in need of a EEC (4) module to fit a '90 F150 Lariat XLT with a 4.9L inline with EFI. I believe that is the correct one. It is located behind the drivers kick panel. I have opened it up and it has leakage in a couple of places. This is a farm truck so I'd like to keep the price down if I could. I don't have a clue on where to look for one. Thought about a salvage yard but don't know how good one of those would be. Thanks for any help.

Write down the numbers on your existing PCM:
That photo was clipped from here: Fuel Injection Technical Library » EEC Program Codes
Most salvage yards and other suppliers will reference the Ford number, from the first photo example: E7SF-12A650-A1B. It also helps to have the Code (DA1) too.
You can look for one from a salvage yard, or Ebay or other online sellers. Pop in the Ford part number into a search, you may be amazed at what you can find.

The challenge in going the junkyard route is that whatever you find will also likely have failed capacitors. And if by chance they haven't, they may be on the verge of failing.
A truly rebuilt unit, or one you replaced the capacitors on yourself, would be the best bet.

The 3-digit code - the one circled in each of the three pics - that's the one you want want from your truck.
It's not as imperative to match it if you have a manual transmission, which is why I asked.

I disagree. For lesser known Catch Code PCMs you stand very little chance finding one in an internet search IMHO.

The Ford Part Number in that example is E9ZF-12A650-AA. In some cases it's easier to filter your search by using E9ZF-AA.

I think you are misunderstanding the previous response. It is highly recommended to start looking for a PCM, used or rebuilt, using the Ford Part number.
The PCM controls the engine and the transmission if the vehicle has a transmission that is electronic controlled such as the E4OD. A manual transmission equipped vehicle or one with a mechanical transmission, AOD/C6/etc., are less strict on matching up the numbers.
Do yourself a favor, look for and procure one that matches exactly. Less headaches in the long run.
