ecm replacement

i have a 1995 F150 xlt flareside 351w 5.8L v8, this also may be relevant, i had a new engine and transmission with a heavy duty kit put it 3 years ago.

so i was driving on the highway and it started to smoke in the cabin and stalled, i was able to make it a mile from my house before it completely died on me having to get it towed the rest of the way home, so yesterday i tried to read the codes with a jumper wire and had no check engine light flashing, so i took out the ecm and it was fried. pictures below:








so i need to find this part but having trouble with the label what series of numbers/letters should i be looking at to find this part

Couldn't even begin to unravel the meanings behind all those numbers and letters. The F5TF number is the Ford part # for that specific ECM.
You can look it up by that part number - google sends you to rockauto who is out of stock - but they seem to want well over 250 plus shipping and extras no doubt.
PM me if you have no luck - I have a few ECM's I may have a 95 that could work.

Cheapest I found it for was $200, A remanafactuerd one from advanced auto,
http://m.advanceautoparts.com/mt/sho...searchTerm=pcm

It seems that in any picture I have seen of this ecm it's always the same transitor that blows out, these remanufactured ones are supposed to be improved by having their known issues fixed, so it might be wise picking this one up so it doesn't happen in the future or I was thinking about checking the junkyard down the street from me if I can get on for cheap

I did receive a recall notice on the truck about the cruise control sponiously combusting but never got around to getting it fixed, maybe what happened to me was what they meant

I think the unit under the hood was what cooked on the c/c recall. You should take it in though - it's a 20 minute fix. had mine done.
If you go to the junkyard you'll want a truck your year of course - you may have trouble finding a 5.8 truck, but the 5.0 in 95 was an HO, so same firing order as the 5.8 so it should run your truck and theoretically the computer should compensate for any fuel needs difference when it reads the o2 sensor.
Big thing to watch for is matching up the transmission - they're controlled by the pcm (sometimes called the ecm, but that's the early ones) at least the automatics are. Trans code is found on the driver's door post sticker - "E" is E4OD and "u" is 4R70W (AODE).
Can't mix and match the computers as far as the trans goes.

now I have a new engine and transmission so I do t know if I trust what it says on the door, does it say on the trans anywhere I could lay under and look if so, I think though he just rebuilt the trans, I don't really remember

Unlikely he would have put a different one in (lots of other things to change) but 4R70W has about 14 bolts holding the pan on, E4OD has about 20

You better get the cruise recall done, it's for a leaky disconnect switch on the master cylinder. This can short out and set the whole truck on fire. Power is on that switch even with the engine OFF and key removed.

Disconnect the switch till you get it done.

If the switch isn't leaking, they will install a harness jumper with an inline fuse. If it's leaking, they will replace the switch.

This is what happens when it shorts out:
