All models are equipped with a shift-lock system. System locks gear selector in Park unless brake pedal is pushed down. Shift-lock actuator uses an integral relay to release a solenoid (mounted on gear selector assembly).
On 1994 Miata, a key interlock solenoid and control unit prevents ignition key from being removed unless gear selector is in Park. With ignition key removed, gear selector locks in Park.
On all other models, a mechanical control cable prevents ignition key from being removed unless gear selector is in Park.
