The truck harness doesn't match up with the Mustang computer nor will it attatch to the dash harness. So you can't use that. I believe you can use the engine harness but not the EFI/EEC harness. So you'll need to find a late 92 or 1993 5.0 EFI harness. Another option is to hack it in...it can be made to work but a 5.8 EFI bone stock is only (IIRC) 15 or 20 more HP than a 5.0-and uses twice as much fuel (they were turds and used a ton of fuel...most guys who looked at a F250 or F350 either got the 460 or a diesel). You get the idea. The upper intake won't clear the hood either. And most aftermarket uppers won't work with the truck lower-so then you have to get both.
No matter which way you look at it, it's not going to be plug-n-play....unless it's possible to find a Mustang 5.0 engine & harnesses (better to get the whole car), fuel lines, everything to swap into yours. Granted it'll still only be a 5.0 but probably quite a bit quicker than a stock 5.8 will ever be...

Dont take any of the advice from above, jus cause sum1 like the 5.0 better than the 351 doesnt make it better. I thought you said u have the computer and all so the only real pro might be the dash hookups. Im satisfied your not gonna leave it stock so u dont have to worry bout a stock 5.0 being any quicker, trust me, you'll have alot of fun with the windor!! Oh and by the way does 439rwhp and 473rwtq sound like a turd?
If u do wanna use the 351 EFI, u might wanna get sum drop motor mounts, and if u got a 2.3 t5 u can also use it but when u get the clutch for it jus chuck the pilot bearing cause u cant use it, u'll need 2 get a pilot bearing for a 1983 ford ranger, 2.2 diesel.
WOW. With 439 HP and 473 torque? I bet that's a beast! What's it run? 12.50-ish?
I didn't say I liked the 5.0 better. Well...I take that back. A 5.0 EFI has it's place and a relaxing, fun, quick Fox body is meant for a 5.0. However, a 351w based engine (nowhere near a stocker) is fun too. The thing is...swapping in a 351 is quite a bit more expensive/time consuming and overall more trouble initially than a 5.0 is. And....though they can be built to run like a raped ape, typically a stock iron headed 5.8 with even a cam and headers is still a dog. Been there done that, not proud of spending that much on something that wouldn't get out of it's own way, but it was what it was. FYI even the 1995 F150 (was it a roller? Can't remember) 5.8L engine was only 210 HP and 325 lb-ft. The 5.0 Mustang in 95 was 215 HP. If we can't add, the 5.0 had 5 more HP than the F150 did. And anyone who's driven an F150...or for that matter an F250 with a 5.8 knows that they're nothing to write home about. Most people that got the 5.8 wished they'd gotten the 7.5 which got better mileage, more torque, and more HP. The 351 is a much better engine from the get go, but in stock form they are dogs, plain and simple. Low RPM, low HP, low torque, gas guzzlers. With exhaust and intake upgrades they'll make over 300 easily but then again so will a 5.0. Start swapping heads and going stroker...then that's where the 351 shines brightly over a 5.0.
BUT...keep in mind that there's plenty of folks on here that run 5.0 engines that make WAY more than 400 HP (myself included) and enjoy the lighter weight of the engine, the better fuel economy and the ease of servicing as compared to a 351 in the same vehicle. And then theres those of us who still run 5.0's and even though less HP than maybe our buddy's 514, we still smoke them at the drag strip. That's FUN-and reminds me of a little 2.3 Mustang I had that played heck with some of those same big block cars. The look on their face after getting their posterior handed to them by a smaller (in my case MUCH) smaller engine with LESS power was priceless. It's all about what you want. If you want a stock 351 fine go for it but don't expect it to be anything to write home about.
And trying to hack a TRUCK 5.8 EFI into a Mustang is not impossible but I guarantee before it's all said & done, you'll wish you'd have gotten a Mustang harness with it's plug-and-play capability
So u think that u can get more power out of a 302 come on man!! I dont recall him saying he was gonna do any thing to the motor b4 he put it in but he didnt say he wasnt either. Why do a swap like that and leave the egine stock???? Go with the 351 man, trust me You'll be alot happier with it.
Yeah make Way more than 400Hp until you start blowin the " lighter 302 " to pieces! HP is bragging rights, Tq is what gets u off the line did the 95' musdtang have 325flb tq? Not to mention I believe the F350 was jus a bit heavier than the mustang. Come on manWOW. With 439 HP and 473 torque? I bet that's a beast! What's it run? 12.50-ish?

TO answer the OP original question.
To swap the 351 into your Car and keep it Fuel injection the correct way here is what you need. I dont care about what is, or is not done to the engine. I am going to assume it is stock and will suggest parts accordingly.
You will need:
V8 fuel lines from an 86-93 Mustang.
ECU harness from a 91-93 Mustang.
Engine harness from a 86-93 Mustang.
Mass Airflow Sensor from a 94-95 V6, V8 Mustang (70mm works with stock 19lb injectors)
A9L or A9P ECU
Distributor from a Mid 80's 351, Has the TFI Module on the Distrubutor
93-95 F-150 Lighting Lower and Upper Intake, and throttle body ( there are aftermarket varations here, pick your poison here. I am just suggesting factory parts. Plus this will clear the hood without issue.)
351 Swap headers, exhaust is something that you can figure out.
Fox Convertable engine mounts
Stock 19lb injectors
For the front accessories, you can make the stock 5.0 stuff work with a little massaging. Just think it though. You can do it.
90-93 V8 mustang Tachometer. You can re-use your other sensors.
V8 Throttle cable.
V8-sway bars, your car has a tiny front bar and no rear bar.
8.8" rear
These things will get the engine in the car and make it driveable.
if it is an automatic, you will need to swap to a V8 trans, be it a C4, AOD (pre 93, 94+ are AODE and are computer controlled).
If it is a 5-speed you will need a 5.0 Bell housing and a specific pilot bearing (AutoZone: Motormite 14672). Plus a clutch fork for a V8, the clutch, flywheel pressure plate can be sourced from summit or jegs.
If there are any more specific questions, let me know.

Why? It wouldn't be any easier then making it fuel injected! Still a shiload of parts that he would need to get. Plus it wouldn't be worth it. Dropping a carb on it is just dated. You can make the same power with FI, plus the driveabilty is 1000% better. My 93 was carbbed when I got it. Wouldn't start when its below 50 outside, plus it loaded up, and just didnt run well unless WOT. When I swapped the all the fuelie stuff over, it would start at sub 0 temps and idle fine, drove great and gets awesome mileage. Show me a carb mustang that does that...
I also forgot to mention:
You will need an Oil pan from a 91 Crown Vic Police interceptor with a 351W, along with the pickup. It uses the same style double hump pan as the mustang.
What do u call "awesome mileage"? If you dont go overboard on the size and have a good shop tune it for you, you can get some good mileage out of a carb setup to.
To the OP
Some very good advice ^
Those are the parts you'll need to do this right. If you choose to go carb, that's a different set of parts. But the engine harness and computer from the truck will not work because the truck harness won't mate to the mustang dash harness. You might be able to use the truck injector harness though.
U guys act like its rocket sience to put a carbed 351 in a fox. And its not, Iknow people have different ideas about how to do it, but its not that hard.... Build it the way u want to, cause ur the 1 thats gonna be driving it. Im not bashing the FI though!!!
He bought an engine, efi computer and efi engine harness....safe to say he's interested in doing an efi swap.
If he decides he wants carb, then he can decide for himself and ask the question. But why this is turning into a carb vs efi debate is beyond me. That's not what the OP asked. His question was pretty black and white.
whats sup guys sorry for replying soo late well i dont know if i wanna do carbs or efi i was planingdoing somthing simple maybe a stock rebuilt with a cam some heads intake and carbs not looking to spend 2 or 3000 in the motor something that sound mean and run strong what also looking for used heads soo if u guys can help me out with combos
Either way, carb or efi, your gonna have fun with it after u get done pullin your hair out. LOL. you can get remand heads from flootek pretty cheap, last I check you could get a pretty good set for around $700 a set. But Id go with Patriot. They are good heads for a great price. Edelbrock E-street heads are a good Buy to for around $900 a set. You can also get a set of GT40p heads and and put some good springs in them after u have he heads checked, they flow pretty good, and are way better than an E7 heads that wud be the cheapest way to go, but they are'nt near as good as the patriots or edelbrock. It jus depends on what ur budget alows for. As far as tha Intake, you have to decide weather u wanna carb it or inject it.
iam going with carbs and which is a better head Patriot or Edelbrock E-street heads i might do somthing down the road as performance which head would help me out the most. gt40p heads every 1 in there motor and grandmother have them heads now what cam should i go my bother got the e303 cam i dont like how it sound like its not choppy enuff i want somthing that u can hear i want the body of the car to shake hard lol
