Engine Crankshaft Position Sensor Connector for GM Applications

Standard Ignition S-959 is an engine crankshaft position sensor connector built for repairing damaged or heat-affected wiring at the sensor connection point. It uses high-grade materials to support consistent conductivity and a secure electrical connection on vehicles such as the Chevrolet Colorado, GMC Canyon, and Hummer H3.

Key Features

  • Male connector with female pin socket terminals
  • 2-wire design for crankshaft position sensor circuits
  • 16-inch harness length for repair routing
  • Includes butt splices for wire repair
  • Built for electrical connector replacement on ignition and sensor harnesses

Detailed Description

This Standard Ignition S-959 connector is a direct repair solution for crankshaft position sensor wiring where the original plug has cracked, corroded, or lost terminal integrity. It is engineered with durable materials to help maintain stable signal transfer between the sensor and engine harness. This part cross-references AC Delco 1P2646 and Delphi EC431 for the same application. Standard Ignition S-959 is a practical choice for restoring sensor connection quality on GM trucks and SUVs that rely on a dependable crankshaft position signal.

What It Helps Fix

  • Broken or brittle crankshaft position sensor connector housings
  • Intermittent sensor signal caused by poor terminal contact
  • Corrosion at the electrical connection point
  • Wiring damage near the sensor pigtail
  • Check engine lights related to crankshaft position sensor circuit faults

Installation Notes and Tips

Use proper wire-stripping and crimping practices when splicing the harness. Match wire routing to the original layout to reduce strain on the connector and keep the repair away from heat sources and moving components. Verify terminal engagement and secure the connection before clearing fault codes and testing the circuit.

Quality Assurance

Standard Ignition draws on decades of electrical parts development and uses high-grade materials to support reliable conductivity and consistent fitment. The brand’s pigtails and sockets are developed to address common failure points found in original connectors.
