| | Standard Color | Function | Details / Notes | | :--- | :--- | :--- | :--- | | B+ | White / Red | Battery / Memory | Connects directly to the car's 12V battery for constant power, preserving memory settings and allowing the unit to turn on. | | ACC | Red / Yellow | Accessory / Switched | Connects to a circuit that receives 12V only when the ignition is in the "ACC" or "ON" position. This triggers the head unit to power up. | | GND | Black / White | Ground | The essential ground connection to the vehicle's chassis, completing the electrical circuit. Without a proper ground, the unit won't function. | | ILL+ / ILL+B | Green | Illumination (+) | An uncommon feature on many Toyota units. This wire provides the positive voltage to dim the unit's display when the car's lights are turned on at night. | | ILL- | / White | Illumination (-) | The negative reference wire for the dimming circuit. This suggests the PZ071 uses a differential or dedicated dimming control system. | | FL+ | White | Speaker (+), Front Left | Positive terminal for the front left speaker.
