Toyota Harrier (ASU60 / ASU65) Option Connector Pinout

[Roland.O]

If you want to cleanly install aftermarket accessories—such as dashcams, radar detectors, or ambient lighting in the Harrier ASU60 / ASU65, this document provides the OEM pinout data to safely locate unswitched battery lines, ignition-switched power, illumination signals and chassis grounds. It is essential for power and ground verification, circuit tracing and connector identification when utilizing the vehicle's pre-wired aux ports. Attempting to tap into the aux power or connect auxiliary equipment such as dashcams etc without the factory pinout runs the risk of short circuits, blown integration fuses and incorrect wiring identification. This can damage sensitve multiplex comm circuits or the accidental deployment of airbags due to incorrect circuit overload.
