Heavy-Duty GM Starter & Ignition Solenoid Connector

This GM Delphi Single Pin Connector Kit is designed for starter solenoid and ignition trigger applications across GM platforms and custom harness builds.

Commonly used as a GM starter signal connector, this 1-way plug provides a secure, sealed connection for high-reliability ignition trigger circuits in LS swaps, standalone ECU systems, and motorsport builds.

Featuring a black secondary locking mechanism and large 18–14 AWG terminal capacity, this connector is built to handle higher-current signal applications where smaller sensor connectors are not appropriate.

Common Applications

This connector is frequently used for:

• GM starter solenoid signal wiring
• LS engine swap starter circuits
• Ignition trigger wiring
• Standalone ECU start signal integration
• Custom chassis harness fabrication
• Motorsport ignition systems

Ideal for builders needing a clean, professional solution for starter wiring without resorting to generic spade terminals.
