You need a 90 engine harness for it to be a direct swap. Any other year and re-wiring will be needed..

The 90 harness and 89 harness look very similar. They both have Black & Grey plugs they attacth to the dash harness. But the 90 hanress will have white plugs for the air bag sensors.

so then modification would be needed for 91 -93 mass air harness? anyone else use one of these harnesses on a 90?
