Standard Ignition Neutral Safety Switch P/N:NS-136
Keep your Nissan cranking only when the transmission is safely in Park or Neutral with the Standard Ignition Neutral Safety Switch NS-187. It drops in as a direct-fit replacement for the 1990-1995 Nissan Pathfinder [All], the 1997 Nissan Pickup [All], and the 1999 Nissan Frontier [All].
A neutral safety switch senses the transmission's shift position and completes the starter circuit only in Park or Neutral, helping prevent the engine from cranking while the vehicle is in gear. If a failed switch is the cause of your no-start, replacing it with the NS-187 restores that circuit.
Signs the switch may need replacing include an engine that cranks in gears other than Park or Neutral, or one that won't crank in Park or Neutral even though the battery and starter are good. Because these symptoms can have other causes, diagnose the circuit before ordering.
Manufacturer part number NS-187 (also NS187).
