5. The Fishfinder Control Head outputs NMEA signals through the "pigtail"
cable attached to the end of the GPS receiver cable for connection to
devices such as autopilots. Connect the NMEA Out (White Wire) of the
cable to the NMEA In of the device you are connecting to your Fishfinder.
The pinouts of this cable are as follows:
Red Wire, +12V (output voltage only)

White Wire, NMEA Out.

CAUTION! Please use caution before connecting the red +12V wire to any
other NMEA device. This is an output voltage provided by the Fishfinder unit
and receiver and should only be connected to those NMEA devices that need
a 12 volt input.
