sorry, wrong answer. ask me how I know.....
the 93 has R12 a/c refrigerant, while the 94+ have R134a. the R134a system has a high pressure cutout switch that is not present on earlier cars, and there is wiring for that.
the 93 has different wiring to the wiper motor - 2 connectors rather than 1.
the 95 has different wiring to the rear abs sensors - at the right rear of the engine compartment has a different size connector than the earlier cars.
iirc, there is one other difference that doesn't come to mind at this moment.
depending on which portion of the under-hood wiring the op needs, one or more of these will be in play, and will lead to significant frustration, especially if you don't play this game regularly.
