Wiring Schematics

A wiring schematic is a graphical representation of an electrical system. It outlines in detail the internal components and connections of an electrical system, taking into account factors such as voltage, current, resistance, and wire type. This type of diagram is invaluable for any engineer or technician dealing with electronic systems, as it helps them trace out complex connections and diagnose problems quickly.

FJ Stereo System

The FJ Cruiser stereo system consists of 4 speakers and 1 amplifier. The amplifier is powered by either two 40 amp fuses or three 25 amp fuses, depending on model year and trim level. The speaker sizes vary depending on model, but generally consist of a pair of 5.25” speakers and a pair of 6.5” speakers. The connectors for these speakers are Factory Connectors, which means they’re installed in the vehicle’s wiring harness and connected directly to the amplifier.

Basic Electrical Principles

For someone new to FJ stereo wiring, it is important to have a basic understanding of some basic electrical principles first. Electrical circuits are composed of conductive materials, such as copper wire, that can transfer electrical energy from one point to another. Voltage, measured in Volts (V), determines the amount of electrical power delivered to a circuit. Current, measured in Amps (A), determines the flow of the electrical energy. Resistance, measured in Ohms (Ω), is the material’s opposition to the flow of power and is determined by its size and composition. Together these three factors determine the character of an electrical circuit and the amount of power it can supply.

FJ Wiring Diagram
