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.
