🔧 Automotive Wire Colors and Their Function
This image shows a wire harness with different colors, each with a specific electrical purpose within the vehicle system. Here's what each one represents! 👇

🔴 Power
📌 Carries positive current to different components of the car.
✅ Essential for activating systems such as ignition or electronic modules.

⚫ Ground
🌍 Connects components to the vehicle's chassis, completing the electrical circuit.
✅ Without this wire, there is no current return = the system does not work.

🟡 Signals
📡 Transmits electrical impulses from sensors to the ECU (control unit).
✅ Important for data such as speed, position, or temperature.

⚪ Light
💡 Powers dashboard, interior, or headlight lights.
✅ Turns on and off at the driver's command.

🔵 Battery
🔋 Carries direct current from the battery to various systems.
✅ It is the main power input cable to the system.

🟤 Lighting
🌟 Connects headlights, taillights, and license plate lights.
✅ Ensures visibility and compliance with regulations.

🟣 Turn Signals
🚨 Carries power to the turn signals.
✅ Very important for indicating turns and lane changes.

🔘 Speaker
🔊 Connects the vehicle's sound system.
✅ Carries audio signal from the stereo to the speakers.

⚫⚪ Fuel Pump
⛽ Powers the pump that delivers gasoline to the engine.
✅ Without this signal, the engine does not receive fuel.

💡 Tech Tip:
Always check the vehicle's electrical diagram before working on the wiring. Avoid shorts, failures, or damage to electronic modules!

📌 Useful for: Accessory installation, electrical fault diagnosis, audio or lighting modifications.
