Installs, with included cable ties, to any supression core spark plug wire. The sensor will pick-up the ignition current spike and electronically drive the tachometer. Can be used with all ignitions, like CDI or magneto, where a regular coil with tachometer attachment is not present.

Note: Sensor must be used with interference suppression spark plugs or spark plug caps only.

Note: Not waterproof.

Note: Advised for use with digital stepper motor driven Motogadget tachometers only.
