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.
