GM LS 2-Pin Knock Sensor Connector Kit – Delphi Aptiv Gen 3 (LS2 / LS3 / LS7 / LS9)

OEM-Style Knock Sensor Connector for GM LS Engines

This GM LS 2-Pin Knock Sensor Connector Kit is designed for OEM-style replacement and performance harness construction on LS2, LS3, LS7, LS9, and related Gen 3 / Gen 4 GM engine platforms.

Built using the Delphi Aptiv Gen 3 connector family, this housing includes a secondary locking mechanism and supports 22–20 AWG open barrel terminals for professional harness fabrication.

Knock sensor wiring is critical to ignition timing control and engine protection. Using the correct sealed connector ensures accurate signal transmission and long-term reliability in both street and motorsport applications.

Common Applications

This connector is commonly used for:

• LS2 knock sensor wiring
• LS3 knock sensor harness repair
• LS7 / LS9 engine builds
• Standalone ECU knock input wiring
• Custom LS swap harness construction
• Performance engine management systems

This connector family shares the same housing style used in certain GM flex fuel sensor applications, making it a versatile component in EFI harness builds.
