GM-Thread Pulse Generato r 128K 3-Wire

The GM-Thread Pulse Generator 128K 3-Wire is a precision engine management sensor designed for classic and modern GM vehicles that require accurate crankshaft position and RPM data. This Dakota Digital sensor is ideal for bridging the gap between carbureted and fuel-injected engine platforms, making it essential for digital dash clusters, EFI conversions, and performance engine management systems.

Operating at 128K pulses per revolution, this 3-wire sensor provides exceptional resolution for precise RPM calculation and engine control feedback. It mounts directly into GM distributor or crankshaft trigger applications, reading ferrous wheel teeth or reluctor rings to generate consistent output signals even under high-RPM acceleration or heavy electrical load conditions. Its compact form factor makes integration straightforward in tight engine bays, while the rugged construction withstands vibration, temperature cycling, and fuel system vapors typical of high-performance applications.

Enthusiasts undertaking LS swaps, carb-to-EFI conversions, or digital instrument cluster upgrades will find this sensor essential for maintaining accurate speed and timing signals across the engine's operational range. The 3-wire configuration ensures reliable performance, making it a valuable addition for anyone looking to enhance their engine management system.
