MSD 8950 RPM Activated Switch
Can be programmed to turn on a light, activate a high speed retard or cause an air-shifter to shift by simply plugging in an rpm module. The RPM Switch has two activation wires which, at your pre-selected rpm point, will either ground or open a circuit. No RPM Modules are supplied so they must be ordered separately.
