Garmin 160 BLUE Manual De Usuario

5

The Fishfinder 160 Blue comes with a wiring harness that connects 

the unit to power and the transducer with one easy-to-remove connection.  
Make sure the wiring harness will reach the unit before beginning 
installation.  

If it is necessary to extend the power/data wires, use a wire of compa-

rable size and keep your extension as short as possible.  If the transducer 
lead is too short, DO NOT cut the transducer lead to lengthen the cable.  
This will void the warranty.  Transducer extension cables are available in 10’ 
or 20’ lengths from your GARMIN dealer.

If your boat has an electrical system, it may be possible 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.  

1. Determine the polarity of the fuse holder using a Test Light or Volt Meter.

2.  Install the Red (+) wire on the Positive Fuse Holder Terminal.

3. Install the Black (-) wire on the Negative Fuse Holder Terminal.

4. Install a 2 amp fuse in the Fuse Holder.

During a typical installation, only the Red and Black wires are used.  The 
Blue wire supplies NMEA data, and doesn’t have to be connected for normal 
operation of the unit. The Yellow (alarm) wire is not used, because the Fishfi nder 
160 Blue does not support external alarms.
