Secondary alarm wiring option (Explorer 443df only)
Green Wire: Use this to connect a secondary alarm indicator such as a flashing light or external beeper
with a built-in drive circuit. See the Auto power wiring diagram.
If the external beeper or light requires more than 200 mA total, fit a relay. Consult your Northstar dealer
for more advice.
Fuel kit wiring (Explorer 443df only)
See the Fuel Kit Installation Guide for information about the fuel transducer cable.
Wire the power cable for Auto power (as described in this section) to make sure the fuel counter starts as
soon as the engine starts.
For twin engine installation, a T-connector needs to be installed on the fuel transducer cable.
Auto power option
Black wire: Connect this to the negative
battery terminal.
Red wire: Connect this to the positive battery
terminal after the main switch. Fit a 1 Amp fuse
as shown.
Yellow wire: To enable the engine hours counter
and fuel counter; and to start the fishfinder
automatically when the ignition is turned on,
connect the yellow wire to the ignition system
through a 1 Amp fuse.
Note: The fishfinder cannot be turned off while the
ignition is on.
