Important Considerations
In order for the autopilot to turn on, the yellow wire from the GHC 10 data cable must be connected to the
yellow wire from the CCU/ECU Interconnect cable, and the black wire from the GHC 10 data cable must
be connected to the same ground as the ECU
The ECU can connect to a 12–24 Vdc power source.
The NMEA 2000 power cable must be connected to a 9–16 Vdc power source.
The CCU must be installed in the front half of the boat,
Do not cut or extend the drive unit cables.
If you are using the GHP 12 with a non-Garmin drive unit, you must purchase a GHP 12 drive unit cable
(page 9).
The ECU can either be connected to a 12 or a 24 Vdc battery.
The GHC 10 and the CCU must be connected to the NMEA 2000 network using the included T-connectors
(page 12).
If there is not an existing NMEA 2000 network on your boat, you can build one using the supplied cables
and connectors (page 13).
