3-2-2 Wiring guide

The PILOT 3300 system has two kinds of cables:
The heavy-duty power supply and steering drive usually require high-current cables:
All the other cables are low-current:
When fitting any type of cable:
10
Do not mount any part where it can be used as a handhold, where it will interfere with the operation of the
boat or where it might be submerged.
Do not mount any part where it will interfere with launching or retrieving
the boat.
Do not mount any part within 0.5 m (20") of the plane of a radar antenna.
Mount the compass and gyro:
At least 1 m (3 ft) away from sources of electrical signals or noise, such as the batteries, high-current
cables, other boat cables, engines, fluorescent lights, power inverters, radio or radar transmitters and
antennas.
At least 1 m (3 ft) away from equipment containing a magnet, such as a compass or speaker.
Select the wire gauge from the wire size table (see section 3-4-2).
Fit high-current cables at least 1 m (3 ft) away from other electronic devices in the boat.
Keep the cables as short as possible.
Twin 2 mm (#14) cable is supplied with the PILOT 3300 system and can be used for the high current cable if
its gauge is suitable.
Fit low-current cables at least 1 m (3 ft) away from sources of electrical signals or noise, such as the high-
current cables, other boat cables, engines, fluorescent lights, power inverters and radio or radar transmitters
and antennas.
If the cable for the rudder feedback unit, compass or gyro is too long, do not shorten the cable; instead coil
the cable up near the main control unit.
The cable for the rudder feedback unit, compass or gyro can be extended by adding a 10 m (33 ft)
extension cable and coupling connector. Do not fit more than one extension cable to each unit.
Do not crush, pinch or strain the cable.
Secure the cable at regular intervals.
Ensure no connectors or exposed terminals are in the bilge.
