Product Details

Standard Ignition NS-330 is a neutral safety switch used to control starter engagement only when the transmission is in Park or Neutral. For Acura TL owners searching for a 2004 Acura TL neutral safety switch, 2005 Acura TL neutral safety switch, or 2006 Acura TL neutral safety switch, this part provides the correct electrical interface and mounting style for the listed application. This part cross-references Rostra Powertrain Controls 67-0590 for the same application.

Common Problems It Can Address

  • Engine will not crank in Park or Neutral
  • Starter engages in the wrong gear position
  • Intermittent no-start condition related to the transmission range circuit
  • Faulty park/neutral signal to the starting system
  • Transmission selector position signal issues tied to the switch

Installation Notes

Verify connector shape, terminal count, and bolt-mount location before installation. Inspect the harness connector, shift linkage alignment, and surrounding wiring for wear or corrosion before replacing the switch. Because mounting hardware is not listed as included, reuse or source the required fasteners separately if needed. Confirm proper adjustment after installation so the starter circuit only operates in Park and Neutral.

Quality Assurance

Standard Ignition supplies electrical replacement parts for service applications, and the NS-330 is built to match the listed connector, terminal, and mounting specifications for the Acura TL fitment shown.
