if you get a wiring harness & ecu for the same year as yours
i.e. yours 86-88 yellow plug... get a wiring harness & ecu from a turbo 86-88 or if yours is 89-92 get a grey plug turbo harness from and 89-92 and it should be plug n play
dunno bout the dash side of things tho.. i haven't done an na- turbo swap personally
i think you have to change out the tacho...
anyone else?
