The Toyota 08600 series encompasses a range of OEM head units (including Fujitsu Ten models) commonly used in vehicles from the 1990s through the mid-2000s, such as the Avalon, Echo, and Land Cruiser.
Most of these units utilize the standard Toyota 10-pin and 6-pin connector configuration. Standard Toyota Wiring Color Codes (1987+)

Below are typical wiring diagrams and connector layouts for these systems: Installation Tips
Power Antenna/Amp: If your vehicle has a powered antenna, look for a solid blue wire in the factory harness to trigger the motor.
Safety First: Always disconnect the negative battery terminal before cutting or splicing any wires to prevent short circuits.
Verification: Because manufacturers occasionally changed colors mid-year, use a multimeter to verify constant and accessory power pins before final connection. Wire Almost Any Basic Toyota Stereo

The Toyota 08600 series has a standardized pinout, but there are slight variations between 10-pin and 14-pin connectors. Below, we cover both.
Some 08600 radios (especially those with external CD changer controls) use a 14-pin flat connector. Pinout is as follows:
| Pin | Function | Typical Color | |-----|----------|----------------| | 1 | Left Front (+) | Pink | | 2 | Left Front (-) | Purple | | 3 | Right Front (+) | Light Green | | 4 | Right Front (-) | Blue | | 5 | Left Rear (+) | Black | | 6 | Left Rear (-) | Yellow | | 7 | Right Rear (+) | Red | | 8 | Right Rear (-) | White | | 9 | 12V Constant | Blue/Red | | 10 | 12V Accessory | Blue/Yellow | | 11 | Ground | Brown | | 12 | Illumination | Green | | 13 | Power Antenna | Black/Red | | 14 | Amplifier Remote | Pink/Blue | The Toyota 08600 series encompasses a range of
If your radio has 14 pins and you don’t see a matching color, refer to the metal stamping on the radio case—many 08600 units have the function printed directly next to each pin (e.g., "B+", "ACC", "GND").

The Toyota 08600 series represents a wide range of OEM head units, often manufactured by Fujitsu Ten or Panasonic. Because "08600" is a prefix for many different Toyota part numbers, the exact wiring can vary slightly by model year and vehicle (such as the Corolla, Land Cruiser, or RAV4).
However, most Toyota units from this era use a standardized 10-pin and 6-pin connector system for primary power and speaker functions. Core Wiring Pinout (Standard 10-Pin & 6-Pin)

For those looking for a wiring diagram for the Toyota 08600 radio, I can suggest a few resources that might be helpful. However, I must clarify that I don't have direct access to specific documents or databases that might contain the exact diagram you're seeking. Nonetheless, I can guide you on where to find such information:
Toyota changed their wiring color coding scheme in the mid-90s. If your vehicle is a 1995 model or older, you will likely encounter the "Standard" setup described above.
However, if you are working on a 1996–1999 model (specifically the 08600-00411 or similar variations), the colors are entirely different:
