Description

The Holley Sniper EFI 558-497 is an input/output harness designed for Sniper 2 EFI systems. It provides access to two ground trigger inputs, two ground trigger outputs, a points output, a tachometer output, and a digital gauge output.

This harness features individually labeled wires for easy identification and includes a 5-foot (60-inch) length for its output wires. It also offers an additional 0-5V TPS output, commonly utilized for transmission control units, and a tachometer output wire compatible with most aftermarket tachometers.
