I would say that you can do it. But the question is how much wiring are you going to have to do. I was have computer problems in my '89 a few years back and swapped a sn-95 comp. into it for test purposes. It ran like shit but allowed me to pin the problem on my computer so I replaced it. I'm not sure how much of the wiring is different I know that most of it is the same but the sn-95s have electric fans and other things that won't work with an A9L in the car. Unless you figure out a way to hook it up. So you have to figure out what the differences in wiring are.
