• Blade terminal type with 1 connector, 3 terminals, and male terminal gender
• Direct-fit style replacement for select GM trucks, vans, and passenger cars
• Cross-references Standard Ignition PS-309 for the same application
• Part number 1815414 for ordering and fitment verification

• Electrical connection issues at the oil pressure sender interface
• Replacement needs on GM trucks, vans, and passenger cars with the listed fitments

Installation Notes and Tips

Verify the connector style, terminal count, and thread/application match before installation. Confirm fitment against the vehicle listing for your Chevrolet Silverado 1500, GMC Sierra 1500, or other supported GM model before replacing the original switch. Inspect the harness connector for corrosion or damaged terminals so the new switch can communicate accurately with the ECM.

Quality Assurance
