My '79 Pinto wagon started smoking yesterday. It turned out to be glue melting off a part. I brought the Pinto to the local car care center but they had no idea what the part was or what it does. They called a Ford dealer who also has no idea what the part is or what it does. The car still runs fine (so far) with this part removed. So, can anyone here tell me what this part is, what it does, whether I need a new one, and if so where I can get a new one?
It is a box with what appears to be a computer chip inside covered by amber colored glue. It was located under the dash right above the driver's feet. The text on it appears to read:
Motorcraft
TWO FEEDBACK
ENGINE CONTROL
09EE-12A651-B2B
I have had no luck with this part number.
Here are some photos:

Well, I am no expert on this by any means, but at one point I owned an 80 trunk model that had all kinds of odd things on it, and later learned from reading my chilton, that some cars had engine management systems, which included a few sensors, (that I think had something to do with air temp or flow or something), and a timing control box.
Now remember, I didn't pay a whole lot of attention to this when I read it, as I do not have a car that has all that "junk", but I will check out my Chilton as soon as I get home and try to help you out.
the is a ignition module for a Dura Spark II igintion system ...yah they tend to get old and need replacing. Check with the parts store and get a new one...
It's the Blue Strand module, with the Green Feedback strand.
If they don't know what it is you need to go to a different parts store with your old part not the part number....
Good Luck

Thanks! Do you know where one can be purchased online?
The car still runs with it removed?? I have never seen that before.
What part is burned on it? The amber stuff? You need to look for bad/loose/shorted wires or your new one might do the same.
BTW: The part # is: "D9EE....."
Bill
I wouldn't buy one on line in case you have a issue with the new part you can get a replacement...
Autozone, Napa, Oriellys, Pepboys.......ect...
The Ford Dealer Ship wont carry the part any more but Standard and other ignition and switch manufactures make quality replacements.
What Engine and year car are we talking about...the Feed back control is not super common in 70 at all I think I had a 80 with one on a 2.3.

I retract my earlier statement, (now that I see the picture)that is just the brainbox. Yea, they are common for having "meltdowns", and are cheap to replace. It seems as though some cars never have a problem with them, and others eat them up like crazy. I know of a 78 4x4 that goes through them often enough, that the farmer who owns it keeps one in his glove box.
These are cheap and can be bought anywhere. Like Frank says, be sure that you get the correct one, as there are numerous different ones, but other than wire colors, they all look the same.
ETA: Now that I look at the pictures a little better, I have never seen one with those connectors on it, and also have never seen one mounted inside the car. How big is this? I am starting to suspect that this may not be the ignition box, or at least is one that I have never seen, or seen located where it was. What are the dimensions of this? Is there another one under the hood that looks similar only with two round black connectors about an inch around?
I bet the car is running off another modulal or its be coverted to points and someone didn't remove all the power leads to this unit...other wise there is no way for your car to operate with out this unit in the car.
Take a pic of the drivers side engine compartment and the location this part was mounted. Its not uncommon for people to change stuff around to make a car run and after all its a old car might have had quite a few owners.
FrankBoss
That does make sense, and doing that with power still going to the box might overload it.

Went to Acme Auto Parts today. After an extensive search they could not find one with a blue strand and green feedback. The only one they came up with just had blue and the wiring was different. I'll have to check other places.
That does not look like an ignition module to me. The plugs are different and it would not be located under the dash inside the car.
Can you maybe trace the connecting wire to where they go?
The glue is called conformal coating.
I agree with Tigger. Reason being, I had a '79 wagon back between 1982 and 1984, and it (the ignition module) died on me. Symptom? Car would be driving fine, then all of a sudden would sputter and die. Car would not start again until a few minutes of rest. I replaced it and it fixed the problem.
The location for the ignition module was in the engine compartment, on the passenger side, ahead of the battery, IIRC. The ignition module is not under the dash.

Hey Roger:
The Ford Master Parts Catalog calls it a "CONTROL ASSY. (ENGINE AIR FUEL RATIO)"
and the part number is D9FZ 12A651-A.

It looks like the word "feedback" is on there. May be for a feedback carbureter. I'm not positive, but I believe the feedback carb was one that had computer controlled jets. I had something like that on an old Ranger pickup with a V6. I think the car would run without it, maybe too rich or too lean.
Joe
Yes, that box is for a feedback carburetor, a system Ford called 'three way catalyst' or TWC. Its actually a decent system for that time, but after years of parts swapping who knows? Look for an oxygen sensor in the exhaust manifold, 2 vacuum switches and a vacuum solenoid on the drivers side inner fender. If the carb. you have is made for the TWC system, you are probably running too rich; that is how it defaults, so the car will still run ok, but burn more fuel and emit more CO. (boy do i know this!)
Look through my post from august 2006 in this forum for more info.
