At age 63, I can guarantee that I am a lot more "old school" than you are. Yet even at my advanced age, I have managed to figure out how EFI works well enough to fix it and help others fix their EFI Mustangs too. Since it is Sunday, I will refrain from making any of my usual negative comments about EFI to carb conversions.
The VSS sensor mounted on the transmission speedo gear carrier provides input to the speed control amplifier mounted under the driver’s side of the dash. You will need to make sure that the wiring for the VSS sensor is intact and connected to the speed control amplifier.
The speed control vacuum servo is mounted under the driver’s side fender and uses a push/pull flex cable to connect to the throttle arm. You will need to make sure that you have the push/pull connected to the throttle arm.
The wiring diagram is for a 92-93 model, so some of the wiring colors may be different, but the connections are still the same.

"OLD SCHOOL"
Well at 63 I would have to agree, you are more old school(with all respect). I have done all my mechanic work on all i have owned, but by no means am i an expert, just know what i have worked on. As for efi, yes i have figured it out....with lots of research and you have been the biggest help! I done simple test you told me, pc has ground short, maf not calibrated for injectors, no o2 sensors, aic bad and smoked bad out left bank.
Now being engine needs rebuilt, and the cost of building the efi the way i would want. with my math figures and budget, it is cheaper for me to make a little power house with the carb conversion. Would i have loved to kept it efi, yes without doubt! Nonetheless.......even you have to admit a carburated engine is much easier and cheaper to service!
I do have a block i wish to go all efi, much later on though.
With all this said, I thank you for all your help and support, looking forward to talking with you again!!
I am still curious of your negitive thoughts on carb conversions. Not being sarcastic. Just willing to learn thats all, and you seem to know very much about it. A buddy was asking whats so special about efi cause all he deals in is classic muscle mopars, but i did not have an answer for him?
thanks again j

The EFI vrs carb has been throughly cussed and discussed here on Stangnet, but here are my thoughts...
Carbs are great for the track and make good power. For a strip only N/A car, they are hard to beat. Step on the pedal and flush - it's a gasoline toilet!
EFI RULES on the street for a car that is driven in all kinds of weather, up and down mountains and gets great gas mileage. EFI will make just as much power as a carb and be easier to drive on the street. If isn't hard to tune if you know what you are doing.
There isn't a carb made without computer assist that can do all those things as well as EFI can. The only possible exception would be the IDA or DCOE Webers which cost major $$$ - like $3000 for 4 each IDA 48's and a manifold.
Here's a book that will get you started with how the Ford electronic engine control or "computer" works.
Ford Fuel Injection & Electronic Engine Control 1988-1993 by Charles Probst: ISBN 0-8376-0301-3.
It's about $20 from Borders.com see http://www.amazon.com/ . Select boo...ne in an emissions regulated are, it will be.

I'm also anti carb on an EFI mustang.
First off, they never run as good or consistant.
You have to mess with them, where's if EFI does all the work for you, bolt on 100rwhp and not touch a thing, runs like it just rolled off the showroom floor.
For most people carbs suck in the winter.
Cost is roughly equal to swap from EFI to carb, for some reason people think it's cheaper, but it's not.
For the record, my old combo consisted of a real GT40 tubular intake $200, Ford racing 65 tb and spacer $125, Pro m 75mm meter $100, 24lb injectors $100, and a walbro 155lb pump $59.
Ebay and Craigslist are your friend.
No way you are doing a carb setup cheaper than that.
Besides a used carb is a risk, a used EFI intake is just a non mechanical hunk of metal, so they are all fine.
And worst of all, it completely ruins the cars value.
People that buy 5.0 mustangs are buying it for the 5.0 EFI engine, which is pretty much the simplest Fuel injected engine to work on in existance.
Parts are abundant and cheap.
God forbid you have to sell the car or you are one of those guys that goes from project to project, nobody is going to want a carbed setup.
Just for the record, i read your sig, and you say "major efi troubles". IMHO, there is no such thing.
I've had my car for 15+ years, and not once did i have to pay to have something EFI related fixed, and i'm not a mechanic. It's all sensor related.
It's your car, do what you like, just think long and hard about it, i have made some bad decisions with my car myself, so i know what it's like to have to kick myself in the azz.
