Compatible Applications

• GM / Chevrolet / Buick / Cadillac / GMC: Sensor harness connectors – MAF, MAP, O2, TPS, coolant temperature
• Opel / Vauxhall / Saab: ECU sub-harness and sensor connectors
• Motorcycle: Body harness and sensor connectors using Metri-Pack 150 format

Diagnosis – Common Faults

• P0100–P0118 (MAF/ECT Circuit): Inspect 12124107 connector before replacing sensor – a corroded Metri-Pack terminal is a common root cause on GM platforms
• Terminal back-out: Metri-Pack terminals use a push-to-seat design – a terminal not fully seated will back out under vibration and cause intermittent open-circuit faults
• Terminal removal: Use Delphi Metri-Pack removal tool 12094429 – never use a screwdriver, which will damage the terminal retention lance

FAQ

Q: What is Metri-Pack 150 and how is it different from Metri-Pack 280?
A: Metri-Pack 150 uses a smaller terminal (1.5mm pitch, up to 5A) for signal circuits; Metri-Pack 280 uses a larger terminal (2.8mm pitch, up to 9A) for higher-current circuits such as lighting and solenoids. Never mix terminal sizes between series.

Q: Is GM 12124107 a Delphi or Packard part number?
A: 12124107 is a GM OEM part number. The same connector is supplied by Delphi (now Aptiv) under their own part number system. Both refer to the identical Metri-Pack 150 6-pin connector.
