Gray (universal antenna) that relays the signal to an external amplifier

Black (ground) which ensures that all the components work together effectively

White (illumination) which lights up the display

Violet (blocker) which blocks interference from external sources

Brown (left rear) which is used for the rear speaker for compatibility with amplifiers using the BROWN4 stereo connectors

The color coded wiring diagram is usually included with the instruction manual of the radio, but if it’s not, you can contact the manufacturer to get one.
