In a high-performance race car, your tachometer is your most vital engine-monitoring tool. A loose connection or poor signal quality can lead to erratic RPM readings, missed shift points, and even engine damage.
This harness provides a secure, "plug-and-play" interface between your ignition system and the tachometer head. Engineered to handle the high-vibration environment of a racing cockpit, it features a heavy-duty multi-pin connector that locks into the back of the gauge, ensuring that your RPM data and memory recall functions remain active from the green flag to the garage.
Key Features
-
SMi Series Optimized: Specifically designed to support the advanced features of Longacre Stepper Motor Tachometers, including the high-speed data transfer required for "Peak RPM" memory recall.
-
Vibration-Lock Connector: Features a rugged, locking multi-pin plug that prevents the harness from vibrating loose—a common failure point in standard automotive wiring during dirt track or high-G asphalt racing.
-
EMI/RFI Shielded Design: Constructed to minimize "electrical noise" interference from high-output ignition systems, ensuring a smooth, steady needle movement without "jumpiness."
-
Memory Function Support: Includes the necessary dedicated wiring to power the tachometer's internal memory, allowing the driver to recall the highest RPM reached during a session even after the engine is turned off.
-
Professional-Grade Looming: The wires are encased in a durable, heat-resistant protective sleeve, providing a clean "pro-built" look and protecting the copper from abrasion and engine bay heat.
