How do you put in a tach for escort?

To install a tachometer for an escort vehicle, first, ensure the car is turned off and disconnect the battery. Then, connect the tachometer's power wire to a switched power source, the ground wire to a suitable ground point, and the signal wire to the ignition coil or tach signal output. Finally, secure the tachometer in a visible location, reconnect the battery, and test its functionality. Always refer to the specific installation instructions provided with the tachometer for best results.
