Manual Toyota Fujitsu Ten 86120 Wiring Diagram

The older 86120 units (pre-2006) do not support factory backup cameras or Bluetooth audio. If you see a green 22-pin socket on the back of your unit, that is for a factory CD changer or external navigation module, not a video input.

To add AUX or Bluetooth to these units, you need an FM Modulator (cheap) or a "Toyota Yatour" / "GROM Audio" adapter (expensive but high quality) that plugs into that empty CD changer port.

The Toyota 86120 series, manufactured by Fujitsu Ten, uses a standardized Toyota wiring harness configuration. While specific sub-models may vary slightly, most utilize a two-plug setup: a 10-pin main connector for power and front speakers, and a 6-pin connector for the rear speakers.
