It provides all the necessary power and ground connections for the Sniper EFI and Hyperspark ignition systems, as well as sensors and accessories. The harness is designed to be plug-and-play, requiring minimal modifications to the vehicle's wiring system.

The sensors included in the kit are necessary for the proper operation of the Sniper EFI system. They include a crank position sensor, a camshaft position sensor, an air temperature sensor, an air pressure sensor, and a throttle position sensor. These sensors provide real-time data to the Sniper EFI system, allowing it to adjust fuel delivery and ignition timing for optimal engine performance.
