the optical drive will connect to the power supply with a connector called molex connecter it is a 4 prong connector

SATA power connector is a type of power cable with which we can provide Disks power from the mother board. SATA Power cables are connected from sata point on motherboard to the drive.
It depends on what country and when the installation was made. This is because rules and regulations differ between countries and change over time. The black wire is in other words not always connected to the same thing. Contact a local electrician.

Typically, CD-ROMs are connected using a power connector called a Molex Connector. A Molex Connector has four wires, two for power, the other two for grounding. This connector supplies two different voltages to the device it is connected to - 12v and 5v. For more information on Molex Connectors, see the article here: http://en.wikipedia.org/wiki/Molex_connector#Disk_drive_connector_.28AMP_Commercial_MATE-N-LOK.29
A system will always require a power connector that matches its specific power supply needs, typically a standard connector like the ATX power connector for desktop computers. This connector ensures that the motherboard and other components receive the correct voltage and current. Additionally, systems may also use supplementary power connectors for high-performance components, such as graphics cards. The exact type and configuration can vary based on the system's design and power requirements.
yellow in 12v red is 5v black in ground
This car amplifier has a 9-pin connector. Power wiring: +12V = RED (fat cable) GND(Ground) = BLACK (fat cable) REMOTE = ORANGE (thin cable) Audio wiring, BLACK is connected to minus in this case. BLACK/BLUE = (both are thin) BLACK/WHITE = (both are thin)
the regular ATX has a 20 pin power connector, while the enhanced ATX power connector has 24 pin power connector.
An internal FDD (Floppy Disk Drive) is connected to the power supply via a power cable that typically has a four-pin Molex connector. This connector provides the necessary voltage (usually +5V and +12V) for the FDD to operate. Additionally, the FDD is connected to the motherboard through a data cable, usually a 34-pin ribbon cable, which facilitates data transfer between the drive and the computer system. Proper connection of both the power and data cables is essential for the FDD to function correctly.
In a 2002 Ford Escape XLS, the 12V power outlet is not directly connected to the Diagnostic Link Connector (DLC). The DLC is primarily used for communication with diagnostic tools to access the vehicle's onboard computer systems. The power outlet operates independently, providing power for accessories, while the DLC focuses on diagnostics and troubleshooting.
