2-1/16" CAN-Bus Volt Gauge | 0-18V with Warning | Holley EFI

Holley EFI CAN-Bus Voltage Gauge pulls voltage data directly from the Holley EFI ECU through the CAN network for a cleaner install with no additional sensing wiring required. Built for seamless integration with Holley EFI systems, it delivers real-time voltage data while keeping the setup clean and straightforward. A precision stepper motor keeps the needle smooth, stable, and accurate at a glance, while programmable high and low voltage warnings and a settable warning light add a clear visual alert when readings move out of range. Daisy-chain capability makes it easy to run multiple gauges on the same CAN network. Built for long-term use, it’s made in the USA and backed for life.
