Autometer Tach Adapter for Distributorless Ignitions

AutoMeter is well-known for making reliable gauges and accessories for performance vehicles. This tach adapter is a great example of that, designed to help you get an RPM signal on modern engines where a traditional tach signal isn't readily available. If you're doing a late-model engine swap or working on an application with coil-per-cylinder ignition, this module is what you need to get your tachometer reading accurately.

This unit is fully potted, meaning it's sealed against moisture and dust, and it's built to handle the vibrations you'll find under the hood. It works by sensing the current in the power supply to each coil and then creating a standard 12-volt square wave signal that your AutoMeter tachometer, or other RPM-activated devices, can understand. The wiring is straightforward, with dedicated leads for power, ground, and the signal output.
