GM DENSO 580/LS1 COIL CONNECTOR KIT

GM Denso 580/LS1 Coil Connector Kit — OEM-Compatible Motorsport Wiring Connector

The 68239 is a complete connector kit for GM Denso 580 or LS1 coil-on-plug applications on GM LS1, LT1, and early Gen III engines using Denso 580-style coil connectors. This kit contains the housing, terminal contacts, and retaining/sealing components needed to fabricate or repair a complete GM Denso 580 or LS1 coil-on-plug circuit connection, providing an OEM-compatible interface that mates correctly with the original sensor or actuator connector body.

Why Use Correct OEM-Pattern Connector Kits

When fabricating a race car harness or repairing a motorsport wiring loom, using the correct OEM-pattern connector for each sensor and actuator is essential for both reliability and serviceability. Non-matching connectors require modification or adapters that introduce additional connection points, increase harness complexity, and may produce a mechanically insecure fit that loosens under vibration. OEM-pattern connector kits provide the exact housing geometry, contact type, and locking mechanism designed for the target device, ensuring a secure, vibration-resistant, and correctly-sealed connection that will remain reliable throughout the racing season.

Kit Contents

Each connector kit includes the plug or receptacle housing, appropriately sized crimp contacts rated for the circuit wire gauge, and any wedge locks, seals, or secondary locking components included in the original OEM design. Where the kit description specifies a boot, this provides additional environmental sealing and strain relief at the cable entry of the connector body.

Typical Build Applications

This connector is used for GM LS1 coil-on-plug harness repair and fabrication, early Gen III LS ignition wiring. It is a standard component in professional race car harness builds and engine swap harness fabrication projects across Scandinavia, where correct OEM-compatible connector specifications are a baseline requirement for reliable engine management, data acquisition, and safety system wiring.
