Holley Sniper EFI - HyperSpark Plug and Play Main Harness 558-328
Type: Sniper EFI Main Harness
Our HyperSpark Master Kits were designed to make upgrading your ignition on a Sniper EFI equipped engine simple. When installed with a new Sniper EFI system, the combination creates the easiest to install EFI conversion on the market with only four flying lead connections required. With the included Sniper EFI main harness, you no longer need to run multiple wires to provide switched power for each individual component. Not only does this helps prevent wiring confusion, it will speed up your install time and clean up your engine bay. Just route the harness and pre-terminated connectors to your HyperSpark coil, distributor, and ignition box and plug them in.
Features:
- Harness only requires one connection to a switched power source, battery positive, battery negative, and fuel pump power
- Pre-terminated connectors and built in 40A relay provides power to all of the components within the system
