The Fishfinder 400C comes with a wiring harness that connects 

the fishfinder to power and the transducer with one easy-to-remove 

connection and provides interface capabilities for connecting 

external devices. 
The color code in the diagram (see 

) indicates the appropriate 

harness connections. The replacement fuse is a AGC/ 3AG - 3 Amp 

fuse. If it is necessary to extend the power wires, use 22 AWG wire. 

DO NOT cut the transducer cable, because this voids your warranty. 

If your boat has an electrical system, you might be able to wire the 

fishfinder directly to an unused holder on your current fuse block. If 

you are using the boat’s fuse block, remove the in-line fuse holder 

supplied with the fishfinder. You can also wire the fishfinder directly 

to the battery.

  CAUtION: The Fishfinder 400C maximum input voltage is 35 

Volts DC. Do not exceed this voltage, because this can damage 

the Fishfinder 400C and void the warranty.

  NOtE: During a typical installation, use only the Red and Black 

wires. The other wires do not have to be connected for normal 

operation of the Fishfinder 400C unit. For information on connecting 

to a NMEA or CANet compatible device, see 

1.  Use a test light or voltmeter to determine the polarity of the

voltage source.

2.  Connect the Red (+ or positive) wire to the positive voltage

terminal. (If you use the boat’s fuse block, route the positive

connection through the fuse, as shown on the diagram.)

3.  Connect the Black (- or ground) wire to the negative voltage

terminal.

4.  Install or check the 3-Amp fuse (on the boat’s fuse block or in

the in-line holder).

5.  Align the notches on the cable plug and on the back of the

fishfinder. Insert the cable into the connector, and turn the

lock ring counter-clockwise until it stops.
