Not sure what you said but if both EEC Computers have the same program code then they are the same.
If one works and the other does not then the one that does not work is bad.
I just took an A9J out of a 1989 Van so if you are asking will an A9J work in the 1990 I think it would.
It had a 302 with an AOD transmission.
If one works and the other does not then the one that does not work is bad.

The T2T looks like it came out of a Van with a 5.0 but I would not know what year or if the T2T is an EEC or a PCM Computer.
If the T2T is a PCM it would give error codes if you have an AOD.
If the T2T is an EEC and you have an E4OD then you would have problems with the Transmission.
The A9J is an EEC Computer for the AOD.
What problems are you having with the T2T and what kind of Transmission do you have?
If the T2T is a PCM it would give error codes if you have an AOD.

He must mean the adapter port (where an aftermarket chip would plug in). If the new computer won't run the engine at all then it's faulty. There's no way around it. That or it's an MAF computer and not having the MAF signal is making it not run.

Does your van have the AOD or the E4OD? The E4OD will have a button on the dash for overdrive and the shift indicator will read P R N D 2 1. An AOD will read P R N OD D 1. Not having the transmission input may be confusing the computer and not letting it run. What was the reason for replacing it? If the TFI module (on the distributor) is failing it won't send the signal to the computer to fire the injectors.

for a cheap price this guy says it came out of a working 1990 ford e-150 5.0 302 eng just like vehicle i have the same he also said it has to be the same
programe code the one i got from him is a9j mine is t2t this one came from
ford bronco f-150 or e-150 5.0 302 eng that works for some reson
