In some automatic (computerized) vehicles there are AUXILIARY POWER CONNECTORS where power has to be supplied from. These connectors are designed by the manufacturer for auxiliary connections.

It is advised to contact with authorized technical services to find out where auxiliary power connector is located in other automatic vehicles
