• If your boat does not already have a NMEA 2000 network,
one can be built using the included NMEA 2000 cables and
connectors (
Building a Basic NMEA 2000 Network for the
Autopilot System
, page 8
).
• To use the advanced features of the autopilot, optional
NMEA 2000 devices, such as a wind sensor, a water-speed
sensor, or a GPS device, can be connected to the NMEA
2000 network.
Power and Data Layout
WARNING
When connecting the power cable, do not remove the in-line
fuse holder. To prevent the possibility of injury or product
damage caused by fire or overheating, the appropriate fuse
must be in place as indicated in the product specifications. In
addition, connecting the power cable without the appropriate
fuse in place voids the product warranty.

Important Considerations
À
Helm control
(or compatible
Garmin
chartplotter)
A dedicated helm control is not included in all
autopilot packages. If you install the autopilot
without a dedicated helm control, the autopilot
CCU must be connected to the same NMEA
2000 network as a compatible Garmin
chartplotter to configure and control the autopilot
system.
Á
Helm control
data cable
This cable should be installed only if you are
connecting the autopilot to optional NMEA 0183
devices, such as a wind sensor, a water-speed
sensor, or a GPS device (
NMEA 0183
Connection Considerations
, page 9
).
Â
NMEA 2000
power cable
This cable should be installed only if you are
building a NMEA 2000 network. Do not install
this cable if there is an existing NMEA 2000
network on your boat.
The NMEA 2000 power cable must be
connected to a 9 to 16 Vdc power source.
Ã
NMEA 2000
network
The helm control or compatible Garmin
chartplotter and the CCU must be connected to
a NMEA 2000 network using the included T-
connectors (
NMEA 2000 Connection
Considerations
, page 2
).
If there is not an existing NMEA 2000 network
on your boat, you can build one using the
supplied cables and connectors (
Building a
Basic NMEA 2000 Network for the Autopilot
System
, page 8
).
Item Description
Important Considerations
Ä
ECU
The ECU must be located within 0.5 m (19 in.) of
the pump.
The cables connecting the ECU to the pump
cannot be extended.
Å
CCU
The CCU can be mounted in a non-submerged
location near the center of the boat, in any
orientation (
CCU Mounting and Connection
Considerations
, page 2
).
The CCU must be located away from sources of
magnetic interference.
Æ
ECU power
cable
The ECU must be connected to a 12 to 24 Vdc
power source. To extend this cable, use the
correct wire gauge (
Power Cable Extensions
,
page 7
).
Ç
CCU cable
To extend this cable to reach the ECU,
extensions (sold separately) may be necessary
(
CCU Mounting and Connection Considerations
,
page 2
).
This cable connects to the alarm and the
Shadow Drive.
È
Pump
The pump must be located within 0.5 m (19 in.)
of the ECU.
The cables connecting the pump to the ECU
cannot be extended.
É
Alarm
The alarm provides audible alerts from the
autopilot system, and should be installed near
the primary helm station (
Installing the Alarm
,
page 8
).
Shadow Drive
(optional)
Autopilot
switch (not
included)
The Shadow Drive must be installed properly in
the hydraulic steering line, and connected to the
CCU cable (
Installing the Shadow Drive
,
page 8
).
If your autopilot package does not include a
Shadow Drive valve, you should install a manual
Single Pole Single Throw (SPST) switch (not
included) to disable the autopilot if necessary.
