EEC interchangability question

[86drop]

Alright, so the car I'm working on is an '86 LX, originally 3.8, that I have swapped a 5.0 from a '91 into. The EEC I have is from the '91 and I believe it is an A9M. The engine wiring harness is from an '86 and has been converted to a mass air setup. My question is this, is there an EEC that will mate directly to the 60 pin connector of the '86 harness and allow the use of mass air without having to repin the connector to match the EEC? I don't know what year they changed up the 60 pin arrangement but I'm hoping that it didn't coincide with the swap from speed density to mass air. Thanks for any help guys!

All Foxbody MAF EEC's are pinned the same.

A few years ago my 86' LX former pursuit vehicle has been changed from speed density to MAF w/ a 1991 harness and EEC (A9P). A Tweecer was also installed after conversion. The EEC now needs to be replaced. Having difficulty finding an A9P (w/ the exception of junk yard hunting) we have done a lot of research including the link Ford Fuel Injection. We ordered and purchased a U4PO based on a Cardone number. The main difference here is this EEC is meant for AODE and my LX has an AOD. We're thinking because the Tweecer will change the programming anyway, it should work. Any thoughts as to whether there will be an issue there?
