This plug-and-play harness is specifically designed to support aftermarket high-capacity in-tank fuel pumps by addressing the limitations of the factory fuel pump control module.

 

Key Features:

Enhanced Current Handling:

  • Factory fuel pump control modules are designed for the current demands of stock low-pressure fuel pumps.
  • Aftermarket high-capacity fuel pumps draw significantly more current, which can strain or overheat the factory wiring.
  • This harness resolves this issue by incorporating an additional grounding mechanism.

 

Secondary Ground Connection:

  • Includes a dedicated secondary ground wire to offload excess current safely.
  • The ground wire must be connected to the factory ground bolt location in the C pillar area, ensuring a secure and reliable connection.

 

Plug-and-Play Design:

  • Requires no cutting or splicing of the factory wiring, simplifying installation while preserving the integrity of the original wiring system.

 

Benefits:

  • Prevents Overheating:

    • The additional grounding ensures that the OEM fuel pump wiring can handle the higher current demands of aftermarket pumps, reducing the risk of overheating and potential damage.
  • Safe and Reliable Operation:

    • Allows the use of high-pressure fuel pumps without compromising safety or performance, ensuring consistent fuel delivery for high-power applications.
  • Non-Invasive Installation:

    • The plug-and-play design eliminates the need for extensive modifications, making this harness a practical and user-friendly upgrade.

 

Installation Notes:

  • Grounding Requirement:
    • The secondary ground wire must be securely connected to the C pillar ground bolt to ensure proper functionality and prevent electrical issues.
  • Compatibility:
    • Designed for vehicles with OEM fuel pump control modules that need to be upgraded to handle high-capacity fuel pumps. Ensure compatibility with your specific pump and vehicle model.

 

This harness is an essential upgrade for those running aftermarket high-capacity in-tank fuel pumps, providing a safe, reliable, and non-invasive solution to handle the increased current demands.
