The mundane-sounding components of wires, fuses and connectors
are found in every electrical device, and especially in cars.
Many of the features we have come to expect in our cars are
possible because of these elements, and their reliability has
improved immensely in the last couple of years. Along with
increased reliability, the complexity of car wiring systems has
increased dramatically. Cars now have literally thousands of
circuits. In this article, we'll go through some of the key
components in your car's wiring, starting with the wire itself.
Then we'll discuss fuses and connectors and see how it all fits
