TACH-ADAPT.....the little black box that makes your tachometer work right! This digital tachometer rate adapter makes your existing tachometer display correctly on any four, six or eight cylinder engine. This adapter goes in line with your current tach signal and changes the voltage. The pulse rate conversion feature makes it possible to match your vintage tach to a four, six or eight cylinder engine. This item is easy to install and can be concealed in the instrument panel or mounted to the engine compartment. This item has a four wire connection and works with points, electronic ignition or CDI systems. The pulse restoration allows the tach to to trigger properly from modified ignition systems. The pulse filtering system cleans up waveforms and cleans up erratic behavior. This item fits all models, including 356 models that have upgraded from a 6V system to a 12V.
