Installation Notes and Tips

Verify the terminal style before installation: this switch uses a male blade terminal. Confirm the vehicle’s original connector and mounting style match the OE layout before replacement. For best results, compare the existing switch to the NS709 and inspect the clutch pedal interlock circuit for damage, corrosion, or looseness during service.
