Generally speaking, a relay is an electronically operated switch that allows you to control a circuit with a low-power signal. Almost every system on your vehicle incorporates a relay in its controls, including the starter, electric cooling fans, fuel pump, headlights, and air conditioner, plus accessories like nitrous, off-road lights, and winches.
