⚠️ Required: Holley EFI Gauge Module (Part 554-130) is required to connect the gauge to the ECU (View on Holley.com).

Holley EFI CAN-Bus Tachometer is built to pull engine RPM directly from the Holley EFI ECU through the CAN network for a cleaner install with no coil signal wiring or external tach input required. Designed for Holley Terminator, Dominator, and Sniper EFI systems, it delivers real-time RPM data while keeping the setup clean and straightforward. A precision stepper motor keeps the needle smooth, stable, and accurate at a glance, while daisy-chain capability makes it easy to run multiple gauges on the same CAN network. With classic analog styling, IPX6-rated construction, and a factory-finished look, it’s built for long-term use. Made in the USA and backed for life.
