Gen 2/3 LT/LS O2 Sensor Extension Harness (4-Flat)

Overview

Extends the factory 4-wire flat oxygen sensor connector used on GM Gen II LT (1992-1997) and Gen III/IV LS/Vortec (1997-2014+) oxygen sensor circuits. Useful any time the O2 sensor bung location on your swap headers or exhaust doesn't line up with the factory harness length, giving clean, factory-style reach without splicing into the sensor wiring itself.

• Factory-style 4-wire flat O2 sensor connector on both ends
• Compatible with Gen II LT1/LT4 and Gen III/IV LS/Vortec upstream & downstream O2 sensors
• GM Delphi-style connectors and TXL high-temperature wire to GM spec
