Ok, so I have been searching for a definitive answer on whether or not you could rig a z31 Crank Angle Sensor to work with a z32 ECU? I tried to search it and got numerous results talking about switching the wheels, and how to disassemble them. But this leaves me to believe that the sensors themselves aren't interchangeable (It seems like less trouble just to splice a few wires rather then disassemble one and swap the wheels). So whats the deal?
