Introduction

Installing a Sony car stereo is a great way to upgrade your car's audio system. However, figuring out the wiring can be a daunting task. In this article, we will provide a detailed guide on the Sony car stereo wiring diagram, including the color codes and what each wire is used for.

Understanding the Wiring Harness

The first step in installing a Sony car stereo is to understand the wiring harness. The wiring harness is a set of wires that connect the car stereo to the car's electrical system. It consists of a power wire, ground wire, speaker wires, and other wires that are used for features such as steering wheel controls and USB inputs.

The Sony car stereo wiring diagram uses a standard color code for the wires. Here is a breakdown of the color codes:

• Yellow - Constant +12V
• Red - Ignition +12V
• Black - Ground
• Blue - Power Antenna
• Orange - Illumination
• White - Front left speaker (+)
• White/Black - Front left speaker (-)
• Gray - Front right speaker (+)
• Gray/Black - Front right speaker (-)
• Green - Rear left speaker (+)
• Green/Black - Rear left speaker (-)
• Purple - Rear right speaker (+)
• Purple/Black - Rear right speaker (-)

Connecting the Wires

Once you have identified the wires, the next step is to connect them. Here is a step-by-step guide on how to connect the wires:

1. Connect the yellow wire to the constant +12V wire in your car's electrical system. This will provide power to the car stereo even when the key is not in the ignition.
2. Connect the red wire to the ignition +12V wire in your car's electrical system. This will provide power to the car stereo when the key is in the ignition.
3. Connect the black wire to a ground wire in your car's electrical system. This will provide a path for the electrical current to return to the battery.
4. Connect the blue wire to the power antenna wire in your car's electrical system. This will activate the power antenna when the car stereo is turned on.
5. Connect the orange wire to the illumination wire in your car's electrical system. This will dim the car stereo display when the headlights are turned on.
6. Connect the white and white/black wires to the front left speaker. The white wire is positive (+) and the white/black wire is negative (-).
7. Connect the gray and gray/black wires to the front right speaker. The gray wire is positive (+) and the gray/black wire is negative (-).
8. Connect the green and green/black wires to the rear left speaker. The green wire is positive (+) and the green/black wire is negative (-).
9. Connect the purple and purple/black wires to the rear right speaker. The purple wire is positive (+) and the purple/black wire is negative (-).

Additional Wires

Some Sony car stereos may have additional wires for features such as steering wheel controls and USB inputs. These wires are usually labeled and can be connected to the corresponding wires in your car's electrical system. Refer to the Sony car stereo wiring diagram for specific instructions.

Conclusion

Installing a Sony car stereo is a great way to upgrade your car's audio system. By understanding the wiring diagram and following the instructions carefully, you can easily install your new car stereo and enjoy high-quality audio on the road.
