JVC Car Stereo Wiring Diagrams & Color Codes

Properly understanding the wiring diagrams is critical for car radio installations.

Otherwise, you’ll mix up the wires and plug them in the incorrect slots, which will cause the radio not to work correctly (or not work at all in some cases).

JVC is one of the leading car radio brands. Although their radios come with a straightforward color scheme for the most part, some additional wires (such as parking brake wires) are colored differently across different models and can confuse beginners.

To help you out, we have compiled wiring diagrams and color codes for some popular JVC car radios.

Conclusion

So these were the wiring diagrams and color codes for some popular JVC car radios.

As stated in the beginning, JVC radios have a uniform color coding for most parts, which makes it easy for car installers to identify wires during radio installation/diagnosis.

That said, your particular model may have a slightly different color scheme. So it’s always better to double-check this information from the owner’s manual.
