'91 is going to be your best bet, especially if your the one that bought the computer from me...
i am kenny 
thanks. so will '91 be the only year i can use? i guess they went to the 6.5 in '92 right? so that would probably be a different harness?

I think they went to the 6.5 in '92 or '93 but they were still NA at first so the motor didn't have electronics yet. But the body changed so the wiring could be very different. Best thing to do is compare the computer part # for the different years and compare it to your computer #.
Did you try car-part.com?? Found some interesting stuff on there....
