GHP 10 General Wiring Outline

Notes:

•This diagram is for planning purposes only. Specific wiring diagrams are included in the detailed installation instructions for each component. Hydraulic connections are not shown in this diagram.

•If your boat uses an electrical system that provides more than 12 Vdc, or if you sporadically receive tachometer errors, install an external tachometer filter (010-11399-00). Contact your local Garmin dealer or Garmin product support for more information.

•Connect an optional NMEA 0183-compatible GPS device to the data cable on the GHC 10. See page 32 for more information.

•Connect an optional NMEA 2000-compatible GPS device to the NMEA 2000 network. See page 32 for more information.

* Newer ECU units are compatible with 24 Vdc systems. See page 25 for more information.
