To use any tach..

Dakota Digital DSL-1 $64.75

These Dakota Digital universal diesel alternator tachometer interface units will accept a signal from the W terminal found on some diesel alternators and convert the signal into a tachometer signal for a 4 or 8-cylinder standard ignition system tachometer. These units are adjustable to allow for the different numbers on the alternator, as well as for different pulley sizes on the engine and alternator. Calibration should be done using a light tach or another known reference for speed.
