tit depends, mazda made them low impedance until half way through 87. if you remove the airbox there should be a large metal box with heatsinks on the top of it. it has one black wire and four brown wires coming out of a very large connector. if you have this box then your injectors are low imp. if not then they are high

yes it won't work...

you have to match the ECU + injectors + resister pack


what you need to do is remove and bypass your resister pack now
