Were there any differences in computers between 94-95 Mustang gt 5.0, 5 speed. My 94 mustang has a 95 mustang computer in it. Will this effect anything. I want to know even if it is a very small difference. Thanks

as long as the car it came out of was a manual and your car is a manual or vice versa, your good to go.

ok thanks guys for the info. Now my next question. the computer I have has a jet performance module attached to it. Can I just remove it or was there a stock module in there that I need to have in order for the car to run. Thanks

The EEC itself can't be swapped directly into your 93, no. I'm sure there's a way, but to my knowledge, it hasn't been done. I'm sure it's just the reverse of doing the PIH swap on a 94-95, where we use the A9* series computers in our cars, but it still requires some work.

You can remove it. There was nothing attached to the EEC from the factory.

Ok now, is there a difference between the computer wiring harness's in a manual verse auto car. The reason I ask is because the car was auto and converted to stick so I want to make sure everything electrical is sound before I start doing things. Thanks again

Also, if any one has access to diagrams if there are differences in harnesses I would greatly appreciate if you could get me a link. Thanks

Does your car have a T4 puter in it already, or is this the first time you're putting a T4 puter in the car (it was last driven with a U/W puter)?

The computer thats in the car is out of a 95 gt 5.0 5 speed so im assuming its a t4mo. I cant verify this because the tag is ripped off. I am trying to find out if this was a hack job trans swap or if it was done right. let me know what to look for thanks.

I took the ecm apart. there was no sticker inside. However there was a little circle and it said 95 inside. Im assuming this is the year right? Also, are all 5 speed computers the t4mo or are there a few different ones. Thanks

Guess my memory has failed me once again

Here you go

PCM year dates and strategies and cal file

1988-1993 Mustang = GUFB Strategy = A9L, A3M, A3M1, X3Z, S0Z
1994-1995 Mustang = CBAZA Strategy = T4M0, U4P0, W4H0, J4J1, ZAO

94-95 Stang PCM's

T4M0 = GT stick trans
U4P0 = GT auto trans
W4H0 = GT auto trans
J4J1 = Cobra
ZAO = Cobra R

Ok, so that confirms that if it came out of a 94-95 gt 5 speed then it can only be the T4MO computer. Now how come the GT autos have two different computers?

Some have said it has to do with the supplied rear ratio

yes you can put a mass air meter from a 95 on a 91 92 93 mustang they are direct plug and play! I'm not sure about older ones! the reason i know is i just put one on my 91 and yes they are 70mm!
