I have the chance to buy a 95 mustang gt. Motor has some extras on it not sure what all. But I can buy the whole car with fuel injection, computer and wiring harness. So my question is has anyone done this and how hard is it.

Tough to answer... it all depends on your wrenchworthiness...
A total novice will encounter a steep learning curve.
A well-informed, self determined, and mechanically and electrically inclined individual will find the swap to be challenging yet rewarding.
It also really depends on what engine your truck has. FYI that 95 ecm will most likely need a vehicle speed sensor input, which is tied to the gauge cluster.
A few years back, someone on here swapped a gm tbi system to their 390, and I adapted a quadrajet to mine, so yes anything can be done with the right attitude and determination..
I don't think the vehicle speed sensor will be a issue unless you're trying to use a automatic. The 94-95 stuff was kinda on the dumb side it doesn't have the immobilizer stuff like the later SN cars which is a plus in your case. It's kind of a shame to do away the Efi but in those years you're kinda better off. You say it has extras with it? In past experiences the computer in those things pretty much doesn't like bolt ons and most cases made them slower lol. I'm not saying you shouldn't attempt it but just be aware the 94-95 computer is pretty much a dud.

Where are you on the scale???
.
I'm really self determined for sure. And I have a buddy who is all the other and is willing to help. Do u know HIO if the computer from the mustang will work for a automatic transmission as well. The car is a stick which I don't want to use.

Well by extras I meant it has a e303 cam mass air and gt 40 heads
So factory cobra heads and alphabet cam. I still have one friend that has a car a setup like that. It works but has the typical idle problems and stays overly rich with the same E cam. That car has about every bolt on except but still uses the factory intake. A long time ago I had a bone stock 88 Gt that would usually pull on that thing every time. You get yourself a good computer that's aftermarket it would wake that motor up. You could always put a stock cam in and enjoy. If you can get that one to idle down enough a E cam doesn't sound bad.

As long as you use a tranny that's not electronically controlled. You will need a 50oz flex plate for the proper balance; the older motor you have is likely a 28oz. A cam from a 98/01 explorer 5.0 would be better suited for this. While your at it, so would the gt40p heads. And the intake.
Just buy an 98-01 explorer with 5.0 and you can use engine and transmission. Or use the explorer long block and put a 4bbl carburetor intake on top and go with an aftermarket EFI.
The easiest and cheapest way would be to put a different intake on that mustang motor and use a carb. Use a old style auto and forget about your wiring and tuning nightmare that you most likely will end up with. Then you can still take advantage of having a factory roller cam engine and or course let the e cam in then. I'd be willing to bet the gt40 heads are gt40p from a explorer. Either way it would still work nice and get decent mpg.
The '95 Mustangs had the 104-pin engine processors compared to the '89-'93 5.0L Mustang 60-pin EEC-IV processors (A9L Fox Mustang processor for an engine with a standard transmission or, the A9P processor for an automatic).
If the '95 engine was coupled to an automatic, the engine processor also has a power train control circuit built into it to control the shifting of the electronically-shifted 4R70W transmission.
The '89-'93 engine processors don't have any PCM circuitry in them and the Fox engine processor/wiring harness is more easily adapted to an older vehicle application than the SN95 Mustang processor and wiring harness.
It would be possible though to take the '95 5.0L engine and use the older '89-'93 EEC-IV SEFI MAF processor and wiring harness on it.
I'd be willing to bet the gt40 heads are gt40p from a explorer. Either way it would still work nice and get decent mpg.
The GT40 3-bar heads were installed on the earlier Cobra Mustangs and on the '96-'97-1/4 5.0L Explorers. The GT40P 4-bar heads were installed on the 5.0L Explorers from '97-1/4 through 2001.
Identification of which head type it is is easy to spot. Just look at the ends of the head castings for the "bars". GT40 heads will have 3-bars cast into the ends. GT40P heads will have 4-bars.
This is a set of Explorer GT40P 4-bar heads that I have. You can see the 4-bars on the ends. --there's also a "P" cast on the corner of the heads, just outside of the valve cover flange (above the freeze plug).
I never actually knew the bar thing but I did know about the P casting. It's been awhile since I've even thought about 5.0 stuff. I think when I was still playing with that stuff the Internet wasn't real popular for the most part. I was still getting magazines! Still 5.0 stuff is good fun cheap. I wonder if it would be easier to do a early speed density swap? Stock I always thought they seemed to run better in the 87/88 cars and I guess some 89's.
I still have a set of cobra heads just a little different
