1N4001 diode or similar could be used. It is used to protect the control circuit from the sudden voltage spike. If the relay that you are using has a flyback diode built in, this diode is not needed. '''NOTE: if you are using this schematic without the diode, you risk damaging the device'''.

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.

To build this schematic, you would need to use the same electrical components as mentioned above, only in this case we will use 2 Relays and 2 Diodes. As mentioned earlier, using this schematic without the diode, raises risk damaging the device.
