To have the FISH450 Tricolor turn on automatically
when the boat’s power is switched on, connect both
the yellow and red wires to the boat’s power switch.
Use this in conjunction with the fuel option to ensure
that the FISH450 Tricolor is turned on and
measuring fuel flow whenever the engine is
running. The
Backlight / Power
key will no longer
be able to be used to turn the unit off.
Warning: The FISH450 Tricolor must be run off a 12 volt battery
and must not be run off a circuit without a battery.

The FISH450 Tricolor uses a
colour coded connector
system:
Black connector = Power
Blue connector = Aquaducer
White connector = Fuel
The connectors are bayonet
type, push the plugs into the
sockets then turn the collars to
lock. Make sure the collars are
secure for water tight connection.
Important
• The connection to the
battery must be made via a
fuse (1 amp) or circuit
breaker.
• If possible, route the
transducer cables away
from other wiring on the
boat. Electrical noise from
engine wiring, bilge pumps,
and other equipment can
affect the unit.
• Connect the red wire of the
two-core power cable to
the positive supply and the
black wire to the electrical
ground.
• The shortest and most
direct connection to the
boat’s battery helps to
minimise voltage drop.
• If the
Auto Power
option is
not used, connect the
yellow
Auto Power
wire to
the black ground wire.
