Wiring Diagram Overview
The 97 Honda Civic stereo system has three main components, the radio, the speakers, and the power supply. The power supply consists of a constant power wire, ground wire, and an ignition wire. The radio is connected to the speakers with a series of wires, while the power supply is connected to the radio using another set of wires.
Here’s an overview of the wiring diagram:
| Wire Color | Description |
|---|---|
| Red/Black | Constant Power |
| Black | Ground Wire |
| Yellow/Green | Ignition Wire |
| Gray | Radio Antenna |
| Red/Green | Radio Dimmer Wire |
| Blue/White | Radio Amplifier Turn-On Wire |
| Orange | Illumination Wire |
| Solid Blue | Power Antenna Wire |
Power Supply Connections
Let’s start with the power supply connections. These connections are essential because they supply power to the radio and the speakers.
Constant Power
The constant power wire is always connected to the battery, even when the ignition is switched off. This connection allows the radio to retain its memory settings, such as station presets and clock settings.
The constant power wire is a red/black wire and needs to be connected to the battery positive terminal.
Ground Wire
The ground wire is responsible for completing the electrical circuit and needs to be connected to a metal frame of the car.
The ground wire is a black wire and needs to be connected to a metal frame or bolt.
Ignition Wire
The ignition wire is responsible for turning the radio on and off with the ignition switch. This connection ensures that the radio turns off automatically when the ignition is switched off, preventing the battery from draining.
The ignition wire is a yellow/green wire and needs to be connected to the ignition switch.
Radio Connections
The radio connections are responsible for transmitting the audio signals to the speakers. The following connections are needed for connecting the radio to the speakers.
Speaker Wires
As mentioned earlier, the speaker wires are responsible for transmitting the audio signal to the speakers. The 97 Honda Civic stereo system has four speakers, and each speaker is connected to the radio via two wires, a positive wire, and a negative wire.
The following is the speaker wire color code:
| Wire Color | Speaker |
|---|---|
| Red/Black | Left Front Speaker Positive Wire (+) |
| Green/Black | Left Front Speaker Negative Wire (-) |
| White/Black | Right Front Speaker Positive Wire (+) |
| Violet/Black | Right Front Speaker Negative Wire (-) |
| Blue/Yellow | Left Rear Speaker Positive Wire (+) |
| Gray/Yellow | Left Rear Speaker Negative Wire (-) |
| Red/Green | Right Rear Speaker Positive Wire (+) |
| Brown/Yellow | Right Rear Speaker Negative Wire (-) |
The positive wire is always the wire with the stripe and needs to be connected to the positive terminal of the respective speaker. The negative wire is the wire without the stripe and needs to be connected to the negative terminal of the respective speaker.
Radio Amplifier Turn-On Wire
The radio amplifier turn-on wire is responsible for turning on the external amplifier. This connection is only required if you have an external amplifier.
The radio amplifier turn-on wire is a blue/white wire and needs to be connected to an external amplifier if you use one.
Radio Antenna
The radio antenna connection is responsible for connecting the radio to an external antenna. This connection ensures that the radio receives a clear signal.
The radio antenna wire is a gray wire and needs to be connected to the external antenna.
Radio Dimmer Wire
The radio dimmer wire is responsible for adjusting the brightness of the radio display. This connection is only required if you want the radio display to dim when the headlights are turned on.
The radio dimmer wire is a red/green wire and needs to be connected to the headlight switch.
Illumination Wire
The illumination wire is responsible for turning on the radio display when the headlights are turned on.
The illumination wire is an orange wire and needs to be connected to the headlight switch.
