2
) wires for accessories that use 10 to 20A.

distribution block, or directly to the negative terminal on the battery.
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.

Connecting a Control Input
You can connect to the control terminals to enable the Garmin PowerSwitch device to turn on customizable
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.
