The Main Harness - Universal Un-Terminated from Holley is designed specifically for builders integrating Holley EFI systems into custom applications, including engine swaps and race setups. This harness provides the flexibility needed for precise control over fuel injection and ignition timing.
Engineered with automotive-grade copper conductors and robust insulation, this harness is suitable for under-hood environments. Its un-terminated design allows for full customization of connector placement and wire routing, ensuring that builders can create secure connections tailored to their specific engine bay layout.
Engine builders and serious enthusiasts will find this harness particularly beneficial when integrating Holley EFI systems into non-OEM platforms, such as LS swaps and race engines. The un-terminated construction eliminates the risk of incompatible connectors, allowing for precise and reliable installations.
