My truck is a '88 F150 302 EFI with manual 5-speed.
Doner is a '94 F150 302 EFI , auto ( not sure which one) . Have access to EVERYTHING !! Engine is sold & going to be removed .
Can i plumb in the computer & wiring harness along with the sweet MAF, snorkel & air box & make it work? I know that my '88 is EIC IV , don't know what the '94 is. And will i need to change the dist. ?
Been investigating the mass air thing , but can't afford a decent conversion kit . I can get everything off this doner truck for $100.00

Reason: spelling
Grap the complete wiring harness(dont cut it up.. yet) and computer,the MAF meter, airbox and plumbing. You won't be able to use the computer on your truck without some modification, but you could substitute a mustang computer if you pull the portions of the wiring harness you need and plug them into your '88 harness. Of course the wiring you need is for the injectors and MAF meter, strip the tape and wire loom off the harness once you get it home and remove these portions with the computer pins attached, this can be done with a pin extractor. If you don't know what this is say so and I'll give more details. You don't need a different distributor to make this work.

As in it won't fit the firewall ?? And no.i don't know what a pin extractor is other than a tiny screwdriver to hack at the plug.
To the guy pulling the engine...the MAF meter ,plumbing & air box was all junk. As soon as i mentioned wiring harness & puter....it all became valuable. Perhaps i should just grab the MAF ,air box, & plumbing hard parts & approach the wiring differently with the Mustang computer ??
Very limited funds, so just trying to save a buck. I enjoy wiring work...especially if i'm saving money.

No, all the computers are physically the same size, but the '94 ECU also controlls the auto tranny, and if you put it into your truck without the auto tranny and electronic speed input it will throw codes and operate poorly.

See here.. AMP Insertion/Extraction.....Crawford Tool On Line Catalog & Store These are available at RatShak and electronic supply stores. They simply insert into the back of the connector block around the wire and compress the little barbs that keep the connector in, you can then pull the wire out with the connector attached and undamaged.

That's an idea, you may be able to source the wiring and computer elsewhere for little or no $$.

they have the diagrams for both your 88 computer and the mustang computer.
you can figure out which pins you need to swap on your 88 harness, as well as the extra wires you'll have to add. you can then cut up the harness from the 94, you will need the sequential fuel injector wiring.
follow the diagrams and plug in the mustang computer, and you should be well on your way!
I just found this diagram for adding sequential injection wiring to the truck harness utilizing the Mustang A9L computer. The pin numbers look correct(haven't verified), but you'll notice the injectors are not arranged to match the cylinder numbers. Maybe I'll create a similar diagram with the injectors arranged as they would appear on the motor for clarity sake.

You shouldn't need a pin extractor for the Ford EEC connector -- I used a small flat head glasses screwdriver without any problems and didn't break anything. Not sure about the other connectors mid-way through the harness, though.
i'm taking notes , this be fun. The pins same "style " from '94 tp '88 ?
I take that i should be looking for a A9L puter. Other than A9L & A9P , seen some other '87 5.0 stang puters going for alot less....undesirable i assume .
The pins should be the same, as the computer uses the same 60 pin connector. There are a few catch codes that are pretty much identical to the A9L. I think I had an A3M1 (same as A9L) at one point.

Yes, A9L or A9M are catch codes, others refer to them as boxcodes. Go to this page Ford Software Page and scroll down a little, you'll see boxcodes for many different EEC processors listed, any of those under GUFA, GUFB, or GUFC strategy will work for this type conversion.
