Use this cable with the MEFI 5 Scan or MEFI 5 Scan & Tune systems to interface with vehicles using the flat 6-pin marine diagnostic connector.

The MEFI 5 kits already come with an interface cable for either an OBD2 style connector or a 6-pin flat marine OBD connector. Use this cable if your kit has a OBD2 style connector and you need a marine 6-pin style interface.
