AutoMeter RPM Signal Tach Adapter for Diesel Engines

This AutoMeter RPM Signal Tach Adapter is what you get when you need to add a tachometer or other RPM-based gauges to a diesel engine, or even some gasoline engines with non-standard ignition systems. It's designed to work with AutoMeter tachometers and shift lights, and many other aftermarket devices that rely on an RPM signal. The adapter uses a sensor that mounts to your alternator housing to pick up the engine's rotation.

Installation is straightforward. You'll mount the sensor to the alternator, and then set up the adapter module. A simple push-button interface on the module lets you calibrate it one time to match the alternator signal to the actual engine RPM. This makes it a great problem solver for diesel performance builds or engine swaps where you need your instruments to work correctly. It's a solid option if you're looking to add a tachometer or upgrade your factory gauges.

For a complete diesel-specific gauge setup, consider pairing this adapter with AutoMeter's low-rev tachometer models.
