CENTRA is a car company that needs the CD Player connected to a CD Dispenser connected to a power supply

Special power/control connection can only be disconnected by the company that made the connection.

Any company that makes a connection offers a disconnection service.

Each component has 2 ports for connections.

UNIBUS offers a service for connecting CD components

CENTRA has a service that can connect any CD component to the car chasis via a free port.
