The Trail Tech TTO digital tach/hour meter is designed for universal compatibility with any gasoline engine, eliminating the need for complex wiring harnesses. Installation is streamlined by simply wrapping a single wire around the spark plug, allowing the unit to be mounted in any desired location on the vehicle. This self-contained gauge features an internal battery, ensuring reliable operation without requiring a direct connection to the vehicle's power system.
Beyond basic speed measurement, the TTO provides a comprehensive suite of monitoring tools for both performance and maintenance tracking. The display includes a standard tachometer, a non-resettable hour meter for total engine life tracking, and a separate resettable hour meter to manage service intervals. Additionally, a built-in clock is included, consolidating essential operational data into a single, compact digital interface.
