Couple of 1989 2.3L questions

Hi.
I am getting a Mustang1989 2.3L with fuel injection
non-turbo engine to replace the 2.3L carbed engine in my 79 Pinto.

OK, stop laughing.

Seriously, I want the fuel injection cause I like that better than carbs. That is the main reason I am doing this swap.
Also, I am getting this for $50 cash plus an old power steering rack from a II I am parting out. Hard to turn that down.

Most of the info I have found on the Pinto sites deals with the turbo engine. Hence the questions here.

Question #1. I don't think it is coming with the harness or computer. Is the 1989 Mustang the only car I can get those from, or are there others? And what about aftermarket? I am on a pretty limited budget, or else I would be doing a V8 swap. Gas mileage is an issue as well.

Question #2. This engine is coming with an automatic transmission. What transmission would it be? It will need work, the reverse is out on it.

Question #3. What other transmissions will work without adapting with this engine? I wouldn't mind going to a manual 5 speed. Or even using the 1979 Pinto trans(C3 I think)? Just trying to find out my options at this point.

Question #4. Am I nuts for doing this? From reading here I understand that performance and this engine don't really go together. That is ok, at least for now. For now I am really looking at giving the Pinto an updated drivetrain and doing some needed body work and keeping it cheap. Reliability and driveability are my main goals.

Thanks for any and all advise/opinions.

Cool,thanks!

I already planned on an electrical pump. Putting an efi engine in a Pinto is actually pretty common, but most people go with a turbo version. I figured I would ask here, because you all know this stuff better than Pinto people.

Believe it or not, at least the 79 and 80 do have a return line. Surprised the heck out of me when I was looking for a gas leak. Of course, both of mine need replaced anyway.

Couple of other questions.

Does the wire harness and computer for the efi have to be from a 2.3L engined car, or will any 87-89 work regardless of engine size? I doubt that is the case, but I am a complete noobie to the EFI stuff.

And assuming it does have to be from a 2.3L car, if the engine is gone how can I tell the difference? Anything stand out either with the harness or the computer? And where is the computer on these things? Once I actually get the engine, I am going to be looking for a manual for an 89 Mustang, which hopefully will keep me from having to ask stupid questions to you all here.

One last question re the A4LD trans. Where is the computer on the car and how do I identify it?

Thanks again,
Russ

Thanks, that is a big help.
Hoping to get the engine/trans next weekend. Then the fun starts.
I don't even have an engine hoist yet, so my Blazer may be carrying the engine and trans for a while. Have to wait on income tax refund to get here first.
This will actually be a fairly long term project, so I am not in a big rush. Just need to know what I am looking for if it pops up.
