In open-cockpit racing, dirt tracks, and offshore environments, moisture is the primary enemy of electronic precision. A standard tachometer harness can suffer from terminal corrosion or signal "leakage" when exposed to mud, pressure washing, or humidity. The Longacre 52-43538WR SMi Elite Waterproof Wire Harness is the professional-grade solution designed specifically for SMi (Stepper Motor Instrument) Elite Tachometers that demand a 100% sealed connection.
This "WR" (Water Resistant) series harness features specialized environmental seals at the connector interface, locking out contaminants that cause erratic needle movement or "ghost" RPM readings. Whether you are hosing down a Dirt Late Model after a feature or navigating a rainy road course, this harness ensures your high-speed stepper motor receives a crystal-clear signal from the ignition system to the dashboard.
Key Features
-
Fully Waterproof "WR" Construction: Equipped with high-grade silicone seals and a locking weather-tight connector body to prevent moisture intrusion, even during high-pressure cleaning.
-
SMi Elite Series Optimized: Engineered specifically for the power and data requirements of Longacre’s Stepper Motor Elite Tachometers, ensuring the ultra-fast response time and peak-hold memory functions are fully supported.
-
Vibration-Proof Locking Tabs: Features heavy-duty mechanical clips that keep the harness seated against the back of the gauge, eliminating "pin-fretting" caused by high-frequency engine harmonics.
-
High-Temp Shielded Loom: The wiring is encased in a rugged, heat-resistant sleeve that protects against abrasion and the intense radiant heat found near firewalls and engine blocks.
-
EMI/RFI Interference Protection: Designed to deliver a clean ignition pulse to the tachometer, filtering out "electrical noise" from high-output racing ignitions for a steady, chatter-free needle.
