Diagram | Manual Toyota Fujitsu Ten 86120 Wiring

Most Fujitsu Ten 86120 units use two main connectors:

Some older 86120 units (pre-1998) use a 14-pin combined plug, but the vast majority follow the 10+16 architecture.

If the unit powers on (display lights up, CD spins) but produces no sound:

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. manual toyota fujitsu ten 86120 wiring diagram

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.

Depending on the exact sub-model, the connectors on the back of the radio will vary. Below are the two most common configurations found on the 86120 series.

Configuration 1: The 10-Pin + 6-Pin Setup (Older 2002-2004) Common on early 86120-06010 units. Most Fujitsu Ten 86120 units use two main connectors:

Plug A (Power & Front Speakers): 10-Pin

Plug B (Auxiliary/CD Changer): 6-Pin

Configuration 2: The 20-Pin Setup (Newer 2005-2008) Common on 86120-33250 units and Corollas. Some older 86120 units (pre-1998) use a 14-pin

This single large block or dual blocks contain the same speaker colors listed in Section B. If you have a 20-pin connector, pins 1-14 typically mirror the standard layout, while pins 15-20 are reserved for the external CD changer or auxiliary input.
