That works if your car runs standard ECU, if it runs a standalone ecu you need a little converter that turns the positive square tacho singnal output into a negative peak signal, which will then work with your tacho in the car.

You can run can also use the one black fro the ignitor, thats a designated tacho signal as well and will provide the correct signal to connect to the wire above.
