Wiring Harness Installation
The Fishfinder 160C comes with a wiring harness that connects
the unit to power and the transducer with one easy-to-remove
connection. If it is necessary to extend the power wires, use 22
AWG wire. DO NOT cut the transducer cable, as this will void
your warranty. Transducer extension cables are available 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 supplied with
the unit. You may also wire the unit direct to the battery.
To install the wiring harness:
1. Install the Red (+) wire on the positive battery terminal.
2. Install the Black (-) wire on the negative battery terminal.
3. Install a 2 Amp fuse in the fuse holder (fuse block only).
4. Align the notches on the cable plug and back of the unit.
Insert the cable into the connector and turn the lock ring
counter-clockwise until it stops.
The FF160C outputs NMEA data for: Water Depth, Water Speed and
Water Temperature.
To connect the NMEA output to a NMEA device:
Connect the Blue wire to the Data Input of the NMEA device.
