Seat Belt Harness Connector for GM Applications

The Standard Ignition S-1387 is a seat belt harness connector built for electrical repair work where the original connector has failed, overheated, or become damaged. It uses high-grade materials for reliable conductivity and a secure connection in seat belt circuit repairs across a wide range of GM vehicles.

Compatible With 1993-2009 Buick, Cadillac, Chevrolet, GMC, Hummer, Oldsmobile, Pontiac, and Saturn models, this repair connector is a practical choice for restoring a damaged seat belt harness connection. The S-1387 is designed for technicians who need a direct-fit electrical connector solution for common OE-style repairs.

Key Features

  • Female connector with male blade terminals
  • 2-terminal, 2-wire seat belt harness connector design
  • 16-inch harness length for repair routing
  • Includes butt splices for wire repair work
  • Built with materials selected for consistent conductivity and connection quality
  • Standard Ignition S-1387 for seat belt harness repair applications

Detailed Description

Standard Ignition S-1387 is an electrical connector for seat belt harness repair in GM vehicles, including applications such as the Buick LaCrosse, Chevrolet Impala, Cadillac CTS, and GMC Acadia. It is engineered as a replacement connector for original equipment failures, with a focus on restoring proper electrical continuity in the seat belt circuit. This part cross-references Gates 1300 for the same application.

The connector configuration includes a female housing with male blade terminals, making it suitable for repair work where the original seat belt harness connector has deteriorated or broken. The 16-inch harness length provides added flexibility during installation and routing.

What It Helps Fix

  • Broken or heat-damaged seat belt harness connectors
  • Intermittent electrical connection at the seat belt circuit
  • Corroded or loose terminal contact
  • Damaged wiring at the connector end
  • Failed OE-style connector housings in GM seat belt systems

Installation Notes and Tips

Match the connector style, terminal type, and wire count to the original part before installation. Verify the vehicle’s seat belt harness connector shape and terminal orientation, especially on GM models such as the Chevrolet HHR, Pontiac Grand Prix, and Buick Terraza. Use proper electrical repair practices when joining the harness and confirm a secure terminal fit after installation.

Quality Assurance

Standard Ignition builds its pigtails and sockets with high-grade materials and long-standing engineering focus on technician-driven repair needs. The S-1387 is designed to address common OE connector failure points with a repair-focused electrical solution.
