Connecting the Wiring Harness to Power
1
Route the wiring harness to the power source and to the
device.
2
Connect the red wire to the positive (+) battery terminal, and
connect the black wire to the negative (-) battery terminal.
NMEA 0183 Connection Considerations
• The installation instructions provided with your NMEA 0183
compatible device should contain the information you need to
identify the transmitting (Tx) and receiving (Rx) A (+) and B
(-) wires.
• When the device is mounted in a location that prevents the
internal antenna from acquiring a satellite signal, you can
connect an external GPS19x antenna through a NMEA 0183
connection. For more information, see the
GPS 19x NMEA
0183 Installation Instructions
.
