In a wiring harness, wires of different colors often represent different functions or uses to help simplify installation and maintenance. Common colors and corresponding meanings are as follows:
- Black: Usually used for ground or negative wires.
- Red: Generally represents the positive power line, often used for power input in cars and electronic devices.
- Yellow: Often used for signal lines or power lines, especially in automotive electrical systems.
- Green: Often represents ground or signal return path.
- Blue: Mostly used for signal lines, and may also be used for lower voltage power lines.
- White: Sometimes represents neutral or low-voltage signal lines.
- Brown: Generally represents ground or negative wires, more common in European standards.
- Orange: May be used for auxiliary power or special signal lines.
Different countries or industries may have their own standards, so the specific color definitions may vary. When dealing with wire harnesses, checking the relevant circuit diagram or instructions provided by the manufacturer is the best way to ensure safe and accurate connections.
