Correct Keyway Cam Sensor Connector for GM LS Applications

This GM 3-Pin Cam Sensor Connector Kit is designed specifically for LS cam position sensor applications using the Delphi Aptiv Gen 3 connector family.

This connector features the opposite keyway orientation from the common GM 3-pin MAP and crank sensor connector. Proper keying is critical for correct fitment — these connectors are not interchangeable.

If you are wiring an LS cam position sensor, this is the correct black housing variant.

Common Applications

This connector is commonly used for:

• LS cam position sensor wiring
• LS2 / LS3 / LS7 cam sensor harness repair
• Standalone ECU cam signal integration
• Holley, Haltech, FuelTech cam input wiring
• Custom LS swap harness builds
• Motorsport engine management systems

Cam sensor circuits are critical for sequential fuel injection and ignition timing accuracy. Using the correct keyed connector ensures secure fitment and proper signal integrity.

Connector Specifications

• Delphi Aptiv Gen 3 3-pin housing
• Black housing
• Opposite keyway from GM MAP / crank connector
• Includes secondary locking mechanism
• Accepts 22–20 AWG open barrel terminals
• Sealed design for engine bay durability
• High-temperature resistant construction

Each kit includes:

• 1x 3-Pin Connector Housing
• 1x Secondary Lock
• 3x 22–20 AWG Terminals
• 3x Wire Seals

Everything required for professional harness installation.

Why Keyway Orientation Matters

GM Gen 3 connectors may appear similar across MAP, crank, and cam applications — but the internal keying differs.

Using the incorrect housing will prevent proper engagement and can damage sensor terminals.

Always verify sensor orientation before installation.

Built for LS & Standalone Performance Builds

This connector is ideal for:

• LS engine swaps
