I used by D16Z6 harness on my B16. the only thing you have to worry about is the OBD. if it is a OBD1 car and an OBD2 motor, then you just made more problems for yourself, wiring is way complicated. But if you have the same OBD it is a piece of cake. For OBD 1 make sure that you remember to wire in the knock sensor. and the O2 sensor wires have to be made longer.
