* '''Electromagnetic Relay'''
* '''Electromagnetic Relay'''
Relay choice depends on vehicle's electrical system voltage. If this setup is installed into a Vehicle with 12 V system, then a relay similar to the [https://www.digikey.com/en/products/detail/panasonic-electric-works/CB1-12V/646971 CB1-12V] could be used. Otherwise, if the electrical system is 24 V, a relay similar to the [https://www.digikey.com/en/products/detail/panasonic-electric-works/CB1-24V/646972 CB1-24V] could be used. When choosing a relay, the most important aspect is '''Coil Voltage''', therefore I recommend using aforementioned relays based on the voltage.
Relay choice depends on vehicle's electrical system voltage. If this setup is installed into a Vehicle with 12 V system, then a relay with '''12 V Coil Voltage''' should be used. Otherwise, if the electrical system is 24 V, a relay with '''24 V Coil Voltage''' should be used.
When building this schematic, you can ground the device and the relay on the same spot, for example, chassis of the vehicle.

If you chose the first option, no additional device configuration is needed. If you would like a set up based on the second schematic, you would need to do additional configuring in the device.

===Startup script===
===Setting Output pin state===

First of all, we need a custom startup script to toggle a second relay to ON position. Follow these steps to configure startup behavior:
First of all, we need to set the second relay to ON position by setting the Output pin to High state. Follow these steps to configure default Output pin state:
* Navigate to '''Services -> Input/Output -> Status'''.
* Press on the Output pin state to turn on.

Otherwise, the output pin can be set to high using startup script:
* Navigate to '''System -> Custom scripts -> Startup script'''.
* Navigate to '''System -> Custom scripts -> Startup script'''.
* Above the exit 0 text, input command to turn on the output Pin: ''ubus call ioman.gpio.dout1 update '{"value":"1"}'''
* Above the exit 0 text, input command to turn on the output Pin: ''ubus call ioman.gpio.dout1 update '{"value":"1"}'''
* Press '''Save & Apply'''.
* Press '''Save & Apply'''.

In the new window, configure the settings according to the explanations below.
In the new window, configure the settings according to the explanations below. Here we are not using '''Maintain''' option in order for the relay to be set to ON position once the ignition is on again.
