  • Tachometer trigger wire

    I have decided to use Intelltronix digital gauges in my TJ and ditch the factory ecm. Can anyone tell me if the tach wire in the cummins harness will trigger this aftermarket digital tachometer?

    It should work fine. The Cummins produces a square wave output on the Tach line at 4 pulses per rev, like a V8 engine. This works with the vast majority of aftermarket tachs.
