Toyota 4Runner Circuit Diagram. Electrical Wiring Diagram 96-06

Since it is impossible to include in the manual the EWD of cars of all models and years of production, which are described in this manual, the following are the most typical diagrams that you have to refer to most often.


Before diagnosing any electrical circuit, check fuses, circuit breakers (if installed) to ensure they are in good condition. Check the battery charging and that the battery cable connections are clean and secure.


When checking wires, check that all connections and plugs are clean, with no broken or poorly connected pins. When disconnecting the connection connector, do not pull on the wires, only grasp the connector body.

The electrical system has an operating voltage of 12 volts and uses

negative ground. Power for the headlights and all other electrical equipment comes from a lead-acid battery, which is recharged from the generator.


If your car's stereo player has an encryption system, check if you know the player's activation code before disconnecting the battery.
