Features
Vehicle Compatibility and Return Conditions.
This item was designed and engineered in the USA for US domestic vehicles. OBD tools, ECUs, dongles, programmers, and tuners may have limited compatibility with vehicles outside the USA due to regional differences in emission standards and system configurations. Some features and functionality may vary depending on the vehicle and location.
Some electronic tuning devices and programmers require activation, registration, or pairing with a specific vehicle’s VIN (Vehicle Identification Number). Once activated or paired, these devices may become permanently associated with that vehicle, restricting or preventing their use on another vehicle, resticting our ability to offer returns or exchanges.
Please review the product details and images to ensure it meets your needs. For clarification or assistance, feel free to contact a StreetFX agent. Note: Returns are not accepted for special order or tuning products unless the unit is deemed faulty.
Images are supplied by the manufacturer and may be generic. While all efforts are made to provide accurate pictures, there may be differences in the actual product, such as colour, quantity, version, or included components. Please carefully review the description and specifications for details on inclusions or any variations. Some items may be sold individually or in sets, and images may occasionally depict additional products or quantities not included in your purchase. For assistance or clarification, please contact customer support.

Wire Harnesses, Sniper EFI, HyperSpark, Main Harness, Throttle Body Injection, Plug-n-Play, 40 amp Relay Included, Each
Holley Sniper HyperSpark plug-and-play main wiring harnesses were designed to make upgrading your ignition on a Sniper EFI-equipped engine easy. When this harness is installed concurrently with a new Sniper EFI system, the combination creates the easiest to install EFI conversion on the market—only four flying lead connections required!
Key features:
• Harness only requires one connection to a switched power source, battery positive, battery negative, and fuel pump power
• Pre-terminated connectors and a built in 40A relay provides power to all of the components within the system
• With the included Sniper EFI main harness, you no longer need to run multiple wires to provide switched power for each individual component, which not only helps prevent wiring confusion, but it will also 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
