Eliminates the need to rewire your existing Sniper EFI installation
Want to make the switch from the original Sniper EFI to Sniper 2 and don't want to rewire your system? This harness is designed to do exactly that! The Sniper adapter harness is a plug-and-play solution to connect your existing Sniper 1 wiring harness to a Sniper 2 throttle body. This can be used with any Sniper 2 system that is not equipped with a power distribution module (PDM). Remove your Sniper EFI throttle body from the intake manifold, unplug all of the connectors, and plug the Sniper EFI 2 adapter harness into your existing main harness. Cycle your ignition key, run a fresh wizard on the display of your choosing, and enjoy the benefits of Sniper EFI 2. Sniper EFI 2 is a high-performance electronic fuel injection system designed for a wide range of engines and horsepower goals. It provides improved engine performance, better fuel efficiency, and easier starting, making it the perfect upgrade for any enthusiast looking to take their ride to the next level. With its easy installation and advanced technology, the Sniper EFI 2 is the ultimate fuel injection system for any conventional V8 engine.
