Gen 4/Gen 5 Knock Sensor Extension Harness – 36"

Compact Extension Harness for Relocated Knock Sensor Setups

This 36" knock sensor extension reconnects Gen 4 or Gen 5 sensors to the main harness when sensors are repositioned during engine builds. Uses OEM-spec connectors and is fully plug-and-play.

• Extends knock sensor leads by 36"
• Supports relocated knock sensors on Gen 4 LS and Gen 5 LT engines
• OEM-style terminals ensure proper signal and fit
• Assembled in Wichita, Kansas using OEM tooling, connectors, terminals, and seals to get that audible "click" when the connector is clipped into the harness, just like factory.  We use USA made, TXL wire with factory LS wire colors
• Includes 12” extension harness
• Every wire assembly is tested using a professional-grade harness diagnostic system to verify correct pinout, continuity, and wire integrity, ensuring reliable performance under sustained electrical loads and demanding operating conditions

Note: For replacement knock sensors, use part numbers SEN011 (Gen 4) or SEN012 (Gen 5).

Don’t risk your engine on knock-off connectors that use low-conductivity, tin-plated wire, sloppy crimps and warped terminals. Substandard connections cause voltage drops, misfires and even catastrophic detonation—plus elusive, intermittent faults that turn troubleshooting into a nightmare. Choose OEM-quality seals, terminals and tooling for bulletproof reliability
