Alternators are actually small generators capable of turning mechanical into electrical energy. Driven by the engine belt, alternators use a small signal from the battery to energize a field current that turns a rotor inside a set of stators. Since this energy is driven by the polarity of magnetic fields, the current produced as a result changes direction as the rotor turns, producing current in opposite or alternating directions (hence AC). Alternators produce significantly higher currents than initially supplied by the battery, so they are used to recharge the battery itself and power other electrical components.

A vehicle's stereo system sometimes has a separate amplifier, and when installing a new receiver, you generally need to connect the new stereo's speaker wires to the factory amp's output section. These amp bypass harnesses allow you to use the power from the new car stereo to drive your speakers and not rely on factory power.

The fuse box takes power from the battery, which is in turn charged by the alternator, and protects the wires in the harness against surges that could damage sensitive components. The wiring harness provides a series of connections that allow experienced mechanics and vehicle owners to narrow down problems to specific systems and electrical connections, making it easier to work on the vehicle’s electronics.

Inside the PDC are many fuses and relays which protect and control the many electrical circuits such as fuel pump and fuel injection systems. Fuses are used to safeguard electrical circuits and are designed to pop stopping the voltage flow in the event of a power overload or short circuit protecting the circuit wire from burning.

Make sure it is plugged in, free to move and not burnt or melted. Many of the electrical components on your vehicle can be tested without being removed by measuring a resistance value between certain contacts. If you’re handy with an ohm meter and have a repair manual for your vehicle you can test the component that way.

Modern vehicles often include steering wheel controls to let you safely operate your factory audio system without taking your hands off the wheel. These functions include volume controls, track forward/back, and hands-free calling controls. In most cases, those controls won't work after replacing the factory radio. Thankfully, steering wheel control adapters help integrate these controls with many new stereos, so you can keep using these handy controls with your new stereo.

If your new stereo has a video monitor built in, you will also need to connect a wire to your emergency/parking brake wire. This wire acts as a switch to turn on the video monitor when the parking brake is engaged.
