LS Tach Adapter with Coil Connection Harness
If your LS swap left you without a distributor pickup your tachometer will have no signal and you risk losing vital engine speed feedback. This adapter translates coil pack pulses into a clear tachometer feed and snaps onto LS1 through L99 coil packs without any wiring cuts preserving every factory circuit and eliminating installation guesswork. Internal filtering smooths out voltage spikes and noise so both factory and aftermarket gauges receive stable RPM readings whether you are on the street or the track. A rugged housing and exact fitment keep connections firm in high heat and vibration conditions for reliable performance under all driving demands.
Seamless Integration with Distributorless Ignition
The Tach Adapter harness snaps directly onto LS1 through L99 coil packs, preserving every factory circuit without any wiring cuts. By retaining injector leads and sensor grounds, it prevents unintended faults and misfires that can arise from improper splicing. This true plug and play design not only speeds up installation but also eliminates guesswork, ensuring the original electrical architecture remains intact. Installers can count on a precise fit that aligns with OEM mounting points, reducing the risk of loose connectors and erratic tach readings.
Precision Signal Conditioning for Stable Tach Feedback
Inside the adapter, dedicated filtering circuitry cleans up rapid voltage pulses generated by modern coil packs, smoothing out spikes and noise. This refined output delivers consistent RPM data to both factory and aftermarket tachometers, so shift lights and gauge displays respond accurately under all driving conditions. Accurate speed feedback is critical for preventing overrev events and achieving precise shift timing, especially during track sessions. By translating raw coil signals into a reliable tach feed, the unit enhances driver confidence from street cruising to competitive laps.
Durable Housing Designed for Heat and Vibration
Constructed from premium engineering grade materials, the adapter housing resists the high temperatures found in tight engine bays while standing up to constant vibration. It mounts securely to existing engine brackets, preventing movement that can stress connectors or cause signal dropouts over time. The enclosure also shields sensitive electronics from moisture and debris, ensuring uninterrupted performance in daily driving and demanding track environments. As a result, the assembly delivers long term reliability mile after mile.
Universal Fit Across LS1 through L99 Engines
Designed to support every LS engine variant-from LS1 and LS2 to LS7, LSA, L92, L93 and L99-this adapter standardizes tach integration across a wide range of builds. Builders and professional installers benefit from maintaining a single adapter solution, simplifying parts inventory and reducing compatibility checks. Whether you're working on fresh engine swaps or upgrading existing systems, this versatile harness removes uncertainty and streamlines project workflow. The broad coverage ensures that one unit addresses the needs of multiple applications without extra modules or adapters.
Designed for a perfect fit and dependable RPM signal, this adapter keeps your LS tachometer accurate in every condition.
