Are you converting everything over to mass air? If that is not the case, then no.

If you are converting everything then it will work. Good luck

Bryan - keep me posted on how your MAF conversion goes. We're thinking about doing the same over time to our project car.
Did you get a kit or did you get the harness and computer from a junk yard?

I don't think it will......

When doing a 4cyl to 8cyl EFI conversion we tried a 90 harness in an 87 and it wouldn't work, the fuel pump wouldn't come on. Called a few plces and was told it had something to with the air bag system. Swapped it out for an 89 hanress and the car fired up....
