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.
Item Description
Important Considerations
Helm control
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.
Helm control
data cable
You should install this cable 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 2000
power cable
You should install this cable 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.
You must connect the NMEA 2000 power cable to a 9 to 16 Vdc power source.
NMEA 2000
network
You must connect the helm control or compatible Garmin chartplotter and the CCU to
a NMEA 2000 network using the included T-connectors (
).
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
).
ECU
CCU
You can mount the CCU in a non-submerged location near the center of the boat, in
any orientation (
CCU Mounting and Connection Considerations, page 4
).
Mount the CCU away from sources of magnetic interference.
