O2 Oxygen Sensor Connector Pigtail, Square Female 2-Keyway 4-Wire, OE# 88952839 / PT1631, for GM LS Cars: Corvette (C5/C6), Camaro/Firebird 1998-2002,

Fitment (Square 2-Keyway only): Chevrolet Corvette 1997–2013 (C5/C6; verify square 4-pin), Chevrolet Camaro 1998–2002 Z28/SS, Pontiac Firebird/Trans Am 1998–2002, Pontiac GTO 2004–2006 (LS1/LS2, mostly front O2), Cadillac CTS-V 2004–2005 (LS6), Pontiac G8 GT 2008–2009 6.0L. Use only if your car’s O2 harness uses the square 2-keyway female plug; this is not for the flat 4-wire style. What it is: O2 oxygen sensor connector pigtail — square female, 2-keyway, 4-wire leads (~6 in). Cross/reference numbers: 88952839 (replaces 88953315, 88987901), PT1631. Sensor side (mating component): Mates to 4-wire heated O2 sensors used on the LS cars above when the harness uses the square female 2-keyway plug. Example upstream/downstream OE sensor numbers seen on these platforms include 12569429, 19178930, 19209818 (numbers vary by model/year and position). Confirm location (upstream/downstream) and plug style before ordering. Connector/Pigtail cross references : 88952839 (replaces) 88953315, 88987901; PT1631. All designate a 4-way O2 pigtail for GM applications. Use for search/reference only; the correct fitment depends on having the square 2-keyway 4-pin plug, not the flat 4-wire or other shapes. This pigtail connects to 4-wire heated oxygen sensors on LS cars listed above only when the vehicle uses the square 2-keyway harness plug. Common OE sensor numbers encountered on these platforms include 12569429 (upstream on several LS cars), 19178930, 19209818 (varies by year/position). Always match by connector shape and the sensor’s location (upstream/downstream) before purchase. Wire Harness Length:16CM
