This document provides an overall electrical wiring diagram for a Hilux vehicle. It includes 3 pages of diagrams and labels for various electrical components and their connections, such as the engine control system, combination meter, turn signal and hazard light system, anti-lock braking system, and more. The document uses numeric and alphanumeric codes to identify specific components, their locations, and applicable vehicle variants.
