The Fishfinder 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 page 18) 

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 input voltage is 33 volts DC. Do 

not exceed this voltage, because this can damage the Fishfinder 

and void the warranty.

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.
