Newer Toyota vehicles may use 14-pin, 16-pin, 20-pin, or 28-pin plugs that integrate more functions like steering wheel controls. The same principles apply, but you will need a vehicle-specific adapter or a pinout diagram for those exact connectors. However, if you are working on a (specifically
Your Constant 12V (Battery) and Switched 12V (Accessory) lines are swapped. Ensure the aftermarket Yellow wire is pinned to the Toyota Blue/Yellow wire, and the aftermarket Red wire is pinned to the Toyota Gray wire.
I will cite the sources used. The pinout from result 8 will be mentioned, noting it's for a specific model. The general Toyota wiring information from result 14, 15, and 16 will be used. The guide from result 18 will be referenced for harness details. The adapter information from result 28 and security code information from result 29 will also be included. The final answer will be a detailed, practical article. Toyota part number 08600 represents a specific series of factory-installed (OEM) radios. These units are commonly found in a wide range of Toyota vehicles, including the Land Cruiser, RAV4, Yaris, Corolla, and others, across various model years.
