Detailed Description

Walker Products 270-1002 is built for direct repair of crankshaft position sensor wiring where the original connector has heat damage, corrosion, broken locking tabs, or worn terminals. The pre-terminated pigtail design supports standard crimp or solder repair methods and is made to match the OE connector style without modifying the mating sensor or harness side. This makes it a practical choice for drivability diagnostics and electrical restoration on vehicles such as the 1994-1996 Pontiac Grand Prix, 1994-1995 Buick Century, and 1994-1995 Chevrolet Lumina.
