Ok what you need to find is an 93 ecm harness. Theat will be a plug and play with your wiring in the car now. Look by the ecm plug in the car there is a round grey plug. If it has four wires you have to a very late 92 or 93 harness. If it has six then you can only use a 91 through mid 92 one. i would recommend finding this and making your project alot easier and correct for the 93. Sorry I misunderstood that you all ready had all the 93 dash and wiring in the car.
