How to Upgrade the Classic Holley Sniper EFI to Sniper 2 EFI

Building a Better Sniper

Want to upgrade your original Holley Sniper EFI to Sniper 2 and don’t want to rewire your system? The new Sniper 2 upgrade kits are designed to do exactly that.

Included with each Sniper 2 Plug and Play upgrade system is an adapter solution that connects your existing Sniper EFI wiring harness to a Sniper 2 throttle body in minutes. Simply remove your Sniper EFI throttle body from the intake manifold, unplug all connectors, reinstall the Sniper 2 throttle body, 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 choice, and enjoy the benefits of Sniper 2 EFI.
