Detailed Description

Standard Ignition S-955 is engineered as a replacement oil pressure switch connector for vehicles that use a 2-terminal electrical connection. It is commonly used on applications such as the Chevrolet Impala, Chevrolet Malibu, Buick LaCrosse, GMC Acadia, and Pontiac Grand Prix, along with many other GM models listed in the fitment data. The connector is designed to restore a secure electrical interface when the original pigtail, terminals, or connector body are damaged, corroded, or no longer holding a stable connection.

This part cross-references AC Delco 12126436 and Dorman 645-902 for the same application. Standard Ignition S-955 is part of a broad pigtail and socket program developed for technician-focused electrical repairs, using materials selected to maintain conductivity and consistent terminal engagement.

Common Repair Uses

• Broken or heat-damaged oil pressure switch connector housing
• Corroded terminals causing erratic oil pressure signal readings
• Loose connector fit at the oil pressure switch
• Frayed or damaged wiring near the connector end
• Failed GM pigtail repair on engine electrical circuits

Installation Notes and Tips

Verify the connector style, terminal count, and wire layout against the original part before installation. Use proper splice technique when joining the harness leads, and confirm terminal seating and lock engagement after the repair. For best results, inspect the mating oil pressure switch for heat damage, corrosion, or bent terminals before connecting the new pigtail.

Quality Assurance

Standard Ignition supports this connector with decades of electrical component development focused on technician repair needs. The S-955 is built to address common connector failure points found in GM oil pressure switch wiring repairs and to provide a stable replacement connection.
