The Toyota 86120 head unit series, often manufactured by Fujitsu Ten, typically utilizes a standard Toyota dual-connector system (a 10-pin and a 6-pin plug) for basic power and speaker functions. While specific diagrams can vary slightly by vehicle model—such as the Auris or Corolla—the core pinouts for these Fujitsu Ten units remain remarkably consistent across different Toyota generations. Standard 10-Pin Power & Front Speaker Connector

The larger 10-pin connector (often identified by part numbers like 90980-10996) handles primary power and the front audio stage. Pin 1 (Front Right +): Solid White Pin 2 (Front Left +): Solid Gray

Pin 3 (ACC Power): Red (Provides power when the ignition is on)

Pin 4 (+12V Battery): Yellow (Constant power for memory settings) Pin 5 (Front Right -): White with Black stripe Pin 6 (Front Left -): Gray with Black stripe Pin 7 (Ground): Black or Brown (Connected to the chassis) Pin 8 (Power Antenna): Solid Blue

Pin 9 (Mute): Brown (Lowers volume during calls, if supported) Pin 10 (Illumination): Solid Orange Standard 6-Pin Rear Speaker Connector

The smaller 6-pin connector is dedicated to the rear audio channels. Pin 1 (Rear Right +): Solid Purple Pin 2 (Rear Left +): Solid Green Pin 3 (Rear Right -): Purple with Black stripe Pin 6 (Rear Left -): Green with Black stripe Technical Documentation & Resources

Here’s a concise review of the manual for the Toyota Fujitsu Ten 86120 wiring diagram, based on common user experiences and technical feedback.


Common Problems Solved by the 86120 Diagram

Connector 2: The 6-Pin Secondary Harness (Rear Speakers & Sub)

| Pin | Wire Color | Function | Notes | | :--- | :--- | :--- | :--- | | 1 | Red (Thin) | Speed Sensor | For automatic volume control (rare) | | 2 | Black | Signal Ground | For external amp | | 3 | Brown | Mute Signal | For factory hands-free (if equipped) | | 4 | Blue/Black | Rear Left Speaker (+) | Most common for 4-speaker systems | | 5 | Blue/Yellow | Rear Left Speaker (-) | Most common for 4-speaker systems | | 6 | Pink or Light Blue | Rear Right (varies) | Check specific year |

Important: On many 86120 units, the rear speakers are actually driven by an external factory amplifier (usually under the passenger seat). If you get no sound from the rear, don't blame the 86120 head unit—check the external amp.


Problem 2: "The radio turns off when I turn on the headlights."

The fix: You wired the illumination wire (Green) to a ground. The 86120 expects a positive pulse to dim. Disconnect the green wire entirely. The radio will work fine; you just won't have dimming.

Issue 3: Dim or No Display


5. Quick Testing Without a Diagram

If you’re stuck:

  1. Find constant 12V – pin that stays hot with key off.
  2. Find ACC – pin that gets 12V only with key in ACC/ON.
  3. Find ground – continuity to chassis (<1 ohm).
  4. Speaker wires – pair of wires (usually solid + stripe) for each corner. Test with a 1.5V AA battery – you’ll hear a pop from the speaker.

4. Detailed Wiring Diagram & Pinout

The following data represents the industry-standard "EIA" color codes typically found on the vehicle-side harness (the "pigtail") connecting to the 86120 unit.

What is the Fujitsu Ten 86120?

Before diving into the wiring, it is critical to understand what you are holding. Fujitsu Ten (now known as Denso Ten) is a long-time OEM supplier for Toyota. The number 86120 is Toyota’s internal part number prefix for audio receivers and navigation units.

These are not universal radios. They are built specifically for a particular chassis and model year. For example, a 86120-AA040 from a 2002 Camry will have a different wiring layout than a 86120-52190 from a 1998 Land Cruiser. However, the core wiring color codes and pin functions within the 86120 family share a remarkable amount of similarity, which we will explore below.
