The EMS100 is suitable to work with Yanmar Engines which carry the Yazaki type connector. If your engine comes with a Yanmar panel note that all panels are not compatible. In recent years Yanmar has introduced a engine panel that utilizes the alternator for tachometer, the EMS100 will need an adjustment that can only be made using the DSM250 or the N2KAnalyzer.

Note: The EMS100 wire harness (part # - EMSYRM01) connects between the engine and instrument panel. Most modern Yanmar engines use the rectangular Yazaki connector, but you should verify the type of connector prior to considering purchasing the EMS100 or associated wiring harness.
