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.

Whether you’re assembling an all-new wiring harness, or making repairs to existing circuits, the extensive selection, powerful search tools, and tech expertise at Summit Racing Equipment will help you find the right size and amperage rating of relay for the job.
