This Sniper 2 EFI upgrade kit lets owners of the original Sniper EFI system move up to Sniper 2 without rewiring their vehicle. Simply remove the original Sniper throttle body, unplug the connectors, install the polished Sniper 2 throttle body, and plug the included adapter harness into the existing main harness. This configuration adds an adjustable external fuel pressure regulator, AN fittings, and a 3-foot section of fuel hose so the regulator can be mounted in the engine bay, plus a 5" full-color handheld display for setup and monitoring.
