Toyota Harrier ASU60/ASU65 Headlight Wiring Diagram

[Roland.O]

This factory diagram gives you comprehensive circuit layouts, terminal assignments and the exact wire colour codes for the Harrier ASU60/ASU65 headlights. It gives the schematics needed to trace voltage supply drops and verify ground circuit continuity. It gives the precise pinout allocations and the communication lines linking the headlight ECU to the integration relays, combination switch assembly and left/right lamp units. Without this schematics there is a high risk of incorrect wire identification which can easily short and destroy the expensive ballast or the central body ECU.
