   NOTE: The Garmin Boat Switch device and connected devices will not operate correctly if the plugs are not connected correctly.

X1 Wiring Harness

X1 Primary Wire Connections

The primary wires on the X1 wiring harness connect to the appropriate devices on the vessel to allow for digital control or monitoring. When connecting a device or devices to a wire on this harness, you must use the wire gauge specified in the table at the very minimum. For long wire runs, you should consider using larger-diameter (smaller gauge number) wire to minimize power loss.

NOTE: You should refer to ABYC or your local and regional standards when determining the maximum length and gauge of wire extensions.

1 All switches on the Garmin Boat Switch device must be configured in the chartplotter software to function properly ( Switch Configuration , page 17)

X1 Breakout Wire Connections

The breakout wires on the X1 wiring harness allow you to add a physical switch to a device or circuit connected to a digital switch on the specified primary wires of the X1 and X2 wiring harnesses. Connecting these wires to the CH 32 TANK SENSOR GROUND wire on the X2 breakout wiring harness through a physical momentary switch triggers the associated latching, dimming, or momentary switch for devices connected to the correlated channels on the primary harnesses.

NOTE: Only momentary switches should be used for physical switches. Using physical latching or toggle switches can override the Garmin Boat Switch device and disable digital switching on that channel through the connected Garmin chartplotter.

X2 Wiring Harness

X2 Primary Wire Connections

The primary wires on the X2 wiring harness connect to the appropriate devices on the vessel to allow for digital control or monitoring. When connecting a device or devices to a wire on this harness, you must use the wire gauge specified in the table at the very minimum. For long wire runs, you should consider using larger-diameter (smaller gauge number) wire to minimize power loss.

NOTE: You should refer to ABYC or your local and regional standards when determining the maximum length and gauge of wire extensions.

1 All switches on the Garmin Boat Switch device must be configured in the chartplotter software to function properly ( Switch Configuration , page 17)

X2 Breakout Wire Connections

One grouping of breakout wires on the X2 wiring harness allows you to add a physical switch to a pump or device connected to a digital switch on the specified primary wires of the X1 and X2 wiring harnesses. Connecting these wires to the CH 32 TANK SENSOR GROUND wire on the X2 wiring harness through a physical momentary switch triggers the associated latching, dimming, or momentary switch for devices connected to the correlated channels on the primary harnesses.

The other grouping of breakout wires on the X2 wiring harness is used when configuring the device. Connecting these wires to the CH 32 TANK SENSOR GROUND wire on the X2 wiring harness through a physical momentary switch triggers the associated configuration command.

NOTE: Only momentary switches should be used for physical switches. Using physical latching or toggle switches can override the Garmin Boat Switch device and disable digital switching on that channel through the connected Garmin chartplotter.

Navigation and Anchor Light Wiring

NOTICE

It is your responsibility to comply with applicable laws, regulations, and standards related to the use and/or operation of marine navigation lights. Garmin is not responsible for any fines, penalties, citations, or damages that may be incurred due to any such lack of compliance.

The first three channels on this device can be used for navigation lighting to satisfy the international regulations for preventing collisions at sea. Depending on the navigation-lighting configuration on your boat, you can choose from three different options for activating these lights.

NOTE: You can view examples of common wiring installations including these navigation light options on the Garmin website. Go to garmin.com/manuals/boatswitch/.

Option A (default): One connection for red/green navigation lights, and one connection for white navigation/ anchor lights ( Navigation Lights Option A , page 12).

Option B: One connection for red/green/white navigation lights, and one connection for anchor lights ( Navigation Lights Option B , page 13).

Option C: One connection for red/green/white navigation lights, one connection for steaming lights, and one connection for anchor lights ( Navigation Lights Option C , page 14).

Deactivated: The first three channels are not interconnected, and act as assignable independent switches. These switches can still be used for lighting, but connected lights must be turned on and off independently of one another ( Configuring The Navigation Light Option , page 21).

Navigation Lights Option A

By default, the device is set to this option. Channels 1 and 2 are interlocked and intended for one connection to red and green navigation lights and one connection to white navigation/anchor lights.

• When underway under engine, pressing the switch for channel 2 turns on and off channel 1 (red/green/white navigation lights), and channel 2 (steaming light), and turns off channel 3 (anchor light) if it is already on.
• When at anchor, pressing the switch for channel 3 turns on and off only channel 3 (anchor light), and turns off channel 1 (red/green/white navigation lights) and channel 2 (steaming light) if either are already on.

Connecting to Power

WARNING

The wiring (not included) from the power source to the positive terminal of the Garmin Boat Switch device must run through a 50 A circuit breaker or in- line fuse (not included) as close to the power source as possible. You must connect the positive wire to the fuse or circuit breaker. Connecting the device to power without a circuit breaker or in-line fuse may cause a fire if there is a short in the cable, resulting in property damage and/or serious personal injury.

• If the device is powered by a battery, use a circuit breaker or fuse rated to protect a cable of the gauge used to connect the device to the battery. See the ABYC or your local and regional standards for the required fuse or breaker rating.
• If the device is powered by a source other than a battery, use a circuit breaker or fuse rated to the lower of 50 A or the maximum current of the power source.

CAUTION

A power cable is not provided with this device. You must use 6 AWG marine- grade, fully-tinned copper wire with insulation rated for 105°C (221°F) to connect the device to power and to ground for most installations. For long wire runs, you should consider using larger-diameter (smaller gauge number) wire to minimize power loss. Using the improper wire gauge for the power cable can result in damage to the device, the wiring, and the vessel, as well as causing personal injury.

You should refer to ABYC or your local and regional standards when determining the maximum length and gauge of wire extensions.

NOTICE

The total maximum output of the Garmin Boat Switch device is 50 A.

Power is supplied to the device through two M6 bolt terminals. You must connect the power and ground wires to the bolt terminals using marine-grade ring terminals (not included) to ensure a solid power connection. Connecting bare wires to the bolt terminals may result in loss of power or a short circuit.

1. Route 6 AWG marine-grade, fully-tinned copper wire (not included) to the device and to a ground location on the boat, and select an option:

   • Install a properly rated in-line fuse on the power wire as close to the power source as possible.
   • Identify or install a circuit breaker, as close to the power source as possible, for use with the power wire.

2. Install marine-grade ring terminals on both the power and ground wires.

3. Lift the protector covering the positive terminal.

4. Using a 10 mm (3 /8 in.) socket, remove the nut , lock washer , and flat washer from the terminal bolt .

5. Place the ring terminal at the end of the positive power wire on the terminal bolt.
