Installation Procedures
After you have completely planned the GHP 20 installation on your
boat and have satisfied all the mounting and connecting considerations
for your particular installation, you can begin mounting and connecting
the components.
CCu Installation
To install the CCU, you must mount it to your boat (
), connect it
to the steering system of your boat (
), connect it to a NMEA 2000
), and connect it to the alarm (
).
Installing the CCu Mounting Bracket
Before you can mount the CCU, you must select a location and
determine the correct mounting hardware (
).
The CCU bracket has two portions, the mounting portion and the
securing portion.
1. Cut out the mounting template provided on
.
2. Tape the template to the mounting location.
If you are installing the CCU on a vertical surface, install the
mounting portion of the bracket with an opening
➊
at the bottom.

3. Drill pilot holes at the three mounting locations.
4. Use screws
➋
to secure the mounting portion of the CCU bracket.
Securing the CCu in the CCu Bracket
1. Connect the steering controller
cable and the NMEA 2000 drop
cable to the CCU.
2. Place the CCU in the mounting
portion of the CCU bracket with
the wires hanging straight down
➊
.
3. Place the securing portion of the
bracket over the ball and snap
it into the mounting portion of
the bracket, starting with the
two arms
➋
that do not have the
thumbscrew
➌
.
4. With the cables hanging straight
down, connect the arm with the thumbscrew.
The cables must hang straight down for the CCU to accurately read
your heading.
5. Hand-tighten the thumbscrew until the CCU is held firmly in the
bracket.
Do not overtighten the thumbscrew.
Connecting the CCu
1. Route the five-pin connector end of the steering controller cable to
the steering-system access location on your boat (
).
2. Route the orange and blue wires to the location where you plan to
install the alarm (
).
If the cable is not long enough, extend the appropriate wires with 28
AWG (.08 mm
2
) wire.
alarm Installation
The alarm audibly alerts you to important GHP 20 events.
To install the alarm, you must mount it to your boat (
connect it to the CCU (
).
Mounting the alarm
Before you can mount the alarm, you must select a mounting location
Secure the alarm with cable ties or other appropriate mounting
hardware (not included).
Connecting the alarm
1. Route the alarm-cable to the bare-wire end of the steering controller
cable.
If the cable is not long enough, extend the appropriate wires with 28
AWG (.08 mm
2
) wire.
2. Connect the cables, based on the table below.

3. Solder and cover all bare-wire connections.
Connecting the GHP 20 to the Steering System
of the Boat
Notice
Do not connect the steering controller cable to a NMEA 2000 network.
The GHP 20 requires a powered CAN bus to communicate with the
steering controller. Ensure that the steering controller CAN bus is
properly powered and terminated. Consult the boat manufacturer if
needed.
The steering controller cable allows the GHP 20 Autopilot System to
communicate with the steering system of the boat.
If needed, consult the manufacturer of your boat for assistance locating
the steering-system access.
1. Locate the steering-system access location for your boat.
2. Connect the steering controller cable from the CCU to the steering
system.
If you need to lengthen the steering controller cable, use a NMEA
2000 extension cable.
