CAUTION
Do not connect the accessory ground wires to the ground terminal (GND) on the Garmin PowerSwitch device,
as doing so could result in personal injury or property damage, or could negatively impact device
functionality.
3 Verify that all electrical connections are tight and will not come loose during use.
Connecting a Control Input
You can connect to the control terminals to enable the Garmin PowerSwitch device to turn on customisable
outputs. For example, you can connect your vehicle ignition switch to a control input terminal to turn on
accessories automatically each time you start your vehicle. The control terminals detect a signal from 3.3 V to
18 V. You can configure output functions with the Garmin PowerSwitch app.
Connect the control wire from the control source in your vehicle to one of the two control terminals on the
Garmin PowerSwitch device.
Connecting the Device to Vehicle Power
Before you can connect the device to vehicle power, you must remove the warning tag from the +12V terminal
on the device.
You should always confirm all electrical connections are secure and will not come loose while operating the
device.
1 Connect the large ring end of the included ground wire to the negative terminal on the vehicle battery.
2 Connect the small ring end of the ground wire to the GND terminal
on the device.
