For example, if the connector had a poor connection this would create a resistance problem resulting in heat. This excessive heat melts the wiring insulation allowing moisture to enter and corrode the wiring, resulting in future problems. ***

Overview

On many GM applications, the wiring harness that connects to the fuel module is generally not inspected when completing a repair of the fuel system. This harness is prone to failure and can lead to a misdiagnosis of a vehicle. Loose pins, cracks in the connector housing, and worn wire crimps can simulate symptoms that would be diagnosed as issue with the fuel pump. Holley now offers offers a line of high performance Drop-in fuel modules and wiring connector harnesses to cover a wide ranges of vehicles from sports cars to pickup trucks.

Features:

  • Connector harness design for 12-952 Drop-In fuel module
  • OEM stlye connectors for plug and play installation
  • Designed for return line and pulse width modulation (PWM)
