Michigan Motorsports Gen 4 LS 2-Wire Knock Sensor Pigtail

Repair damaged knock sensor wiring with the Michigan Motorsports Gen 4 LS 2-Wire Knock Sensor Pigtail. This 12" replacement connector is designed to replace common GM knock sensor pigtail numbers S934, PT1804, and 13580877 on many 2005-newer GM applications, including popular Gen 4 LS engines such as LS2, LS3, LS7, L76, LC9, L99, and L96. A damaged, brittle, loose, or corroded knock sensor connector can cause poor sensor communication, check engine lights, timing control issues, and reduced engine performance. This pigtail helps restore a secure electrical connection without replacing the entire engine wiring harness.
Key Features & Benefits
- Gen 4 LS Knock Sensor Repair Connector: Designed for many 2005-newer GM knock sensor applications, including popular LS2, LS3, LS7, L76, LC9, L99, and L96 engine combinations. This is a reliable solution when the factory knock sensor connector is cracked, corroded, broken, or no longer locking securely.
- Restores Knock Sensor Communication: A properly functioning knock sensor connection is critical for accurate detonation detection and ECU timing control. Replacing a damaged pigtail can help correct intermittent sensor faults, check engine lights, reduced performance, and unreliable knock sensor readings.
- 12" Wire Lead Length: The 12" lead gives you enough wiring length to trim back damaged factory wires and create a clean, serviceable splice. This added length is especially helpful when repairing old harnesses exposed to heat, oil, vibration, and general engine bay wear.
- Wide GM Vehicle Coverage: Fits many Buick, Cadillac, Chevrolet, GMC, Pontiac, Saab, and Saturn applications using this 2-wire knock sensor connector style. Because GM used multiple connector designs across different engines and years, verifying the connector shape against the product pictures is important before purchasing.
- Ideal for Repairs, Swaps & Engine Service: Perfect for engine harness repairs, LS swaps, knock sensor replacement, intake manifold service, and general maintenance. This pigtail lets you repair the affected connector end without the time and cost of replacing a larger wiring harness section.
