Keep your starter honest and your transmission in charge with the Standard Ignition Neutral Safety Switch NS-653. It drops in as a direct-fit replacement for the 1999 Plymouth Prowler, restoring the electrical safeguard that lets the engine crank only when the gear selector is in Park or Neutral.

  • Starter safety interlock: Completes the starter circuit only in the Park or Neutral positions, so the vehicle cannot be started while in gear.
  • Direct-fit replacement: A direct-fit neutral safety switch for the listed 1999 Plymouth Prowler application.
  • Straightforward service: An electrical replacement for a switch that can wear or fail internally over time.

Common signs the original switch may need replacing include an engine that won't crank in Park or Neutral, cranking that only works when the selector is jiggled, or a starter that engages in the wrong gear. Because those symptoms can have other causes, diagnose the circuit before replacing. If a failed neutral safety switch is the cause, this NS-653 replaces it.

Frequently Asked Questions

What vehicle does the NS-653 fit?

It is a direct-fit replacement neutral safety switch for the 1999 Plymouth Prowler. Check the Buyer's Guide tab to confirm fitment for your vehicle.

What does a neutral safety switch do?

It allows the starter circuit to operate only when the transmission is in Park or Neutral, preventing the engine from starting while the vehicle is in gear.

Why won't my engine crank in Park?

A worn neutral safety switch can interrupt the starter circuit. Since other faults can cause no-crank conditions, diagnose the circuit first; if the switch is the cause, this part replaces it.

It cross-references CSW550, 4659492AC, and NS7055. Its own manufacturer part number is NS-653.

Should I diagnose before replacing?
