Engine Wiring Harness Connector for GM Applications

Standard Ignition S-1026 is an engine wiring harness connector built for GM vehicles that use a 14-terminal female blade-style connection. It is designed for electrical repair work where the original connector has heat damage, broken terminals, corrosion, or poor contact at the harness interface. This Standard Ignition S-1026 connector is a direct-fit service part for a wide range of Buick, Chevrolet, Oldsmobile, and Pontiac applications.

Key Features

  • Male connector housing with 1 connector interface
  • 14 female blade terminals for engine harness repair
  • Includes butt splices for wire repair work
  • Built with high-grade materials for strong conductivity and consistent connection quality
  • Engine wiring harness connector for electrical, lighting, and body repair
  • Cross-references OE-style part numbers including 12117262 and PT5903 for the same application

Detailed Description

Standard Ignition S-1026 is an engine wiring harness connector used to restore damaged electrical connections in GM platforms. It is a practical replacement when the original connector on the harness side has failed from age, vibration, heat, or terminal wear. The connector uses 14 female blade terminals and is intended for vehicles such as the 2000-2005 Chevrolet Impala, 1997-2004 Buick Regal, and 2004-2008 Pontiac Grand Prix, along with many other Buick, Chevrolet, Oldsmobile, and Pontiac models listed in the fitment data. Standard Ignition focuses on repair parts that address common OE failure points, and this connector follows that approach with materials selected for reliable conductivity and secure terminal engagement.

Common Repair Uses

  • Broken or melted engine harness connector housing
  • Corroded or loose terminal contact at the harness plug
  • Intermittent electrical faults caused by damaged blade terminals
  • Harness repair after heat-related connector failure
  • Restoring proper connection on GM engine wiring circuits

Installation Notes and Tips

Verify terminal count, connector gender, and blade-terminal style before installation. Match the existing harness connector to the vehicle-specific fitment, especially on applications noted as 14-terminal female. Use proper crimping and splicing practices when replacing damaged wiring, and inspect adjacent terminals for heat or corrosion before reconnecting the harness. Confirm the connector shape and cavity layout against the original part before final assembly. Fits 2000-2005 Chevrolet Impala, N/A; Fits 1997-2004 Buick Regal, N/A; Fits 2004-2008 Pontiac Grand Prix, N/A.

Quality Assurance

Standard Ignition builds pigtails and sockets with high-grade materials and decades of electrical repair development focused on technician needs. S-1026 is engineered as a service replacement for original equipment connectors that have failed in the field.
