Locate the existing clutch starter safety switch near the clutch pedal assembly, remove the old switch, and install the new Standard Ignition NS-157 switch in its place. Verify proper alignment and secure mounting to ensure reliable operation. After installation, test the switch by attempting to start the vehicle without pressing the clutch pedal to confirm the safety function is active.
