Install the Control Head
1. Carefully lower the control head into the mounting hole.
2. From under the dash, slide the bracket arms onto the control head. Line up the screw holes on
the bracket arms with the screw holes on the control head (see the illustration below and the
illustration
Installing the Screws
).
3. Install each 3/8" (9.5 mm) screw using a Phillips head screwdriver. Make sure the bracket stays
level and doesn’t block the control head ports.
Hand tighten only
.
4. Hand-tighten each bolt until the end cap is flush against the dash (see the illustration
Securing
the Installation
).
Do NOT overtighten the bolts.
5. Using a wrench, hand tighten each nut so the split-ring washer flattens against the bracket.
CAUTION!
The split-ring washers must be fully compressed for a secure installation.

Route and Connect the Cables
1. See the installation guides included with each hardware component to install power, GPS, and
other optional equipment (transducer, radar, AIS, autopilot, and accessories).
CAUTION!
Do NOT mount the cables where the connectors could be submerged in water or
flooded. If cables are installed in a splash-prone area, it may be helpful to apply dielectric
grease to the inside of the connectors to prevent corrosion. Dielectric grease can be
purchased separately from a general hardware or automotive store.
2. Route the cables to the control head and insert the connectors into the proper ports on the
control head. The ports are labeled and the cable connectors are keyed to prevent incorrect
installation, so be careful not to force the connectors into the ports.
3. Hand tighten the screw nut on each cable to secure the connection. Any unused ports should
be covered with the port covers to prevent potential damage.
4. Apply labels to the cables (optional, not included). Use nylon cable ties (not included) to secure
the cables and create a clean assembly.
5. See the Humminbird Operations Manual to configure the control head.

Cut the In-Dash Mounting Hole
To in-dash mount the ONIX control head, start by placing the hardware on the surfaces where you plan
to install them.
1. Confirm you have the correct In-dash Mounting Template for your control head model.
2. Review the instructions, measurements, and cutting options on the template before you
proceed with the installation.
3. Tape the template to the chosen mounting location.
4. Using the template, select the cutting method that is best for your boat:
Drill one entry hole away from the main cut line that is large enough to insert the blade of your
cutting tool.
OR
Drill a corner hole away from the main cut line using a drill bit that will create a hole as close as
possible to the diameter measurement shown on the template. Repeat for the other three
corners as indicated on the template. Use one of the corner holes as an entry hole, or drill an
additional entry hole away from the main cut line.
5. Carefully begin cutting toward the dotted cut line, and continue cutting to the
inside of the line
around the template.
CAUTION!
The corner cut lines are critical to the installation. Carefully cut along the inside
of the line.
6.
Test the Mounting Hole:
Install the control head in the mounting hole to test the fit. Make
adjustments to the mounting hole as needed. Remove the control head and template when
finished.
7. Thoroughly clean and deburr the mounting hole.

Install the Bracket
1. Install one nut and one split-ring washer onto each 4" (101.6 mm) bolt. See the illustration
below.
2. Insert each bolt into each threaded bolt hole on the bracket. Hand-tighten the bolts until they
are installed approximately 1" (25.4 mm) through the bracket. You will fully tighten the bolts in
a later step.
3. Install one end cap on the end of each bolt.
