Ok I might have made a mistake today when I purchased the motor, it had a wiring harness and computer for a mustang, the donor mustang was still in his garage, but after I got home I noticed the computer says L1C on it, and looking that up it says for a 91-93 tbird non HO motor. Can I use it with putting in a T-5 later? or should I get the A9L computer and use the wiring harness?
they put a non HO motor in a mustang?
If it's for a 91-93 Tbird 5.0, it's an HO...or so I've read and seen with my own eyes.
it says its for a 5.0 maf auto mustang
Man I am confused here to, the motor is from another mustang, but the harness came out of one that was in his garage, I guess someone put the L1c in the mustang or something. Yes it was an auto mustang, but can a 5 speed work with those computers?
sorry, I meant t-bird not mustang

I meant tbird...they were HO in 91-93
Go get your money back, at least for the computer.
L1c is a 91-93 tbird, and a completely different pin setup then a mustang, or 86-88 cat/bird.

where is that thread,,,,,, some guru along with vinnie and a couple other people were just rolling out the A9L this and A9P that and all these different eec types for thier application. I cant find the thread but it was only like in the past 40days may two months but for the life of me i cant find it.....
that might help this guy.
i found this, idk?

EEC types and probably the only resource you need to figure out what computer you need

Here are the pinouts for most efi ford computers

Thanks, that is interesting, I guess I will try and sell the L1c and get a A9L or something
cant it just be re-pinned and used?.... just a thought
For a speed density H.O engine, or Mass Air? If you're keeping the H.O engine basically stock, you really don't need Mass Air.
I guess it could be repined, not sure, but it is for a maf setup.
It could be repinned, but I'll bet the calibration and sensors are different. There would only be about 6 pins I figure to be changed, which would be easy enough to do.
But i'd be worried if you wanted to get it chipped or calibrated later on.
Well I could try re-pin first and and see where it gets me.
I wasn't sure if you were going MAF or not.. might not be worth the trouble to re-pin if your not going that route..
but I would give it a try if I was going MAF.. you have to re-pin and add for the upgrade anyway... Whats a couple more wires
I would get good diagrams for both cars, just to be safe. I'm sure its doable.
Will I need the harness for inside car from the mustang? I read that will use the under hood harness. The Tbird only has the harness from inside the car to the headlights and stuff now. Old harness from the computer to underhood was takin out before me.
I went and printed the pin layout for the 88-93 mustang harness and 91-93 t-bird computer that I have. Looks like re pin will be ok, put I have a question about pin #44 and #49 (R hego gnd and L hego gnd), the T-bird computer does not show a pin location for that. Everything else looks like I can re pin. Any suggestion beside get a A9L, lol?
Also did not see a pin for the #45 Baro (map/bap)?
Phone 5ology tech line, the guy there is a wizard. I think I got the same computer as you thought I would have issues too, I came out alright. I was panicking just like you thinking I got the wrong computer, but there are many different computers that will work. This guy knows all the pins by heart and where they go on the car and he will even phone back to see how your making out.
what is the tech line #? I left a contact request.
Not sure if it is an actual tech line but here is their number (310) 508-8610, I thought the guy I talked to was named Brian, but its been over a year since I talked to them. They will let you know what you need and can hook you up with anything you might be missing or in need of.
Yes his name is brian, I talked with him and he gave some tips, thanks for the info
