You’ll find black wires throughout the vehicle’s wiring harness, but they are typically used to connect components to the ground. In a stereo installation, the black wire is typically connected to the vehicle’s ground wire.

Red Wires

Red wires usually carry a positive charge. They are used to connect the stereo’s power wires to the vehicle’s power source. The red wire is typically connected to the vehicle’s battery or to the fuse box.

White Wires

White wires usually carry a negative charge. They are used to connect the stereo’s ground wires to the vehicle’s ground. The white wire is typically connected to the vehicle’s chassis or to the ground wire.

Yellow and Green Wires

Yellow and green wires are used to connect the stereo’s speaker wires to the vehicle’s speakers. The yellow wire is typically connected to the vehicle’s left speaker and the green wire is typically connected to the vehicle’s right speaker.
