To connect the connector clips to the Unit Switch:
1. From underneath the console, plug the two connector clips from the switch assembly into the two outlets of the
Unit Switch.
NOTE: Connecting the connector clips to the Unit Switch does not require a specific order; either connector will work with
either outlet.
3. Connecting the Power Cable
Connect the Unit Switch power cable to the boat’s fuse panel (usually located near the console). If you must
connect to a battery, connect to a battery switch (not included).
1a. If a fuse terminal is available, use crimp-on type electrical connectors (not included) that match the terminal on
the fuse panel. Attach the black wire to ground (-), and the red wire to positive (+) 12 VDC power. Install a 3 amp
fuse (not included) for protection of the unit. Humminbird® is not responsible for over-voltage or over-current
failures.

1b. If you need to wire the control head directly to a battery, obtain and install an inline fuse holder, a 3 amp fuse
(not included) for the protection of the unit, and a battery switch (not included). Install the battery switch using
the instructions provided with it.
NOTE: If you are unable to obtain a battery switch and are forced to connect the power cable directly to the battery, be
aware that this may cause a slow loss of power over time. See procedure five, Powering Off.
NOTE: Humminbird® is not responsible for over-voltage or over-current failures. The control head must have adequate
protection through the proper selection and installation of a 3 amp fuse.
2. Secure the cables with cable ties (optional).
Your Unit Switch is now ready for operation.
