The unit comes with a wiring harness that connects the unit 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 

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. You can wire the unit directly to the 

battery. If your boat has an electrical system, you might be able to 

wire the unit 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 unit. 

  CAUTION: The maximum unit input voltage is 35-Volts DC. 

Do not exceed this voltage, because this can damage the unit 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 unit. For information on connecting to a NMEA 

or CANet compatible device, see 

page 50.

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

unit. Insert the cable into the connector, and turn the lock ring

counter-clockwise until it stops.
