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.
