AUTO OCCASION Gen 3 LS Knock Sensor Extension Relocation Harness — 41'' for LS1/LS6/LQ4/LQ9/LM7/L59/LR4/L33

Overview

Meet the AUTO OCCASION Gen 3 LS Knock Sensor Extension Relocation Harness, a 41‑inch extension designed to add flexibility to your Gen III knock sensor harness. It helps you manage loom length and positioning, making under‑hood routing more forgiving in tight or heat‑prone engine bays.

What it does

Built to work with Gen III harnesses and blowout sensors, this extension is compatible with a broad family of LS engines and common RPO codes. By providing extra reach, it enables cleaner routing that can accommodate varied engine bay layouts without forcing the original loom.

Key benefits

• 41‑inch reach creates cleaner, longer runs without stressing or bending the existing loom.
• Broad compatibility with Gen III harnesses and blowout sensors across multiple LS engine codes.

Fitment verification and visual match

• Double‑check year, make, and model to ensure the part matches your vehicle.
• Compare detailed photos and specs to your stock harness to confirm a direct fit.

Please review the compatibility notes to confirm this extension matches your specific vehicle configuration. The product is designed to support flexible installation and routing, not to replace sensor function.

Real‑world use cases

During upgrades or maintenance, the extra length can help you route the knock sensor harness away from hot manifolds or crowded sections of the engine bay, potentially reducing wear and simplifying future service tasks.

Durability and compatibility

Engineered to integrate with your existing connectors, the extension aims to remain discreet yet effective under hood conditions, with a focus on straightforward alignment and a tidy final appearance.
