New installation wiring guide

*THIS IS ONLY APPLICABLE TO INSTALLATIONS FOR BOATS THAT HAVE NOT PREVIOUSLY HAD A GAUGE INSTALLED*

FOR OTHER INSTALLATIONS RETURN TO THE MAIN TACHOMETER SUPPORT PAGE

All new installations of tachometers and/or speedometers require installing harness 6Y5-83553-N0-00 from your key/remote to your gauges. This is the only harness needed for speedometers.

Tachometers need a second harness that runs from the motor to your tachometer called the "trim and oil harness". For motors made in 2004 or later you will connect a single 4-pin square plug at your motor (should have at least 1 pink wire) to the to the tachometer through the wiring adapter that came with the tachometer. For motors older than 2004 you will have 2 4-pin connectors at your motor that you need to connect to the tachometer.
