The AutoMeter Diesel Tach Adapter part # 9112 via Marken Performance allows for an easy way to install an aftermarket tachometer on diesel applications or for any vehicle equipped with an alternator that needs an accurate tach signal. AutoMeter’s # 9112 Tach Adapter utilizes a small pick up probe that is strapped to the outside of the vehicle's alternator and inductively reads its rotation. Using the easy, one touch calibration process, the module converts that signal to a 12v square wave signal allowing any AutoMeter tachometer with accurate results.
