Intimidated by automotive wiring? Do you know how to determine the proper wire gauge (or thickness) you need for your job?

In this Summit Racing Quick Flicks video, you will learn how to choose the appropriate wire for your next wiring project.

As an example, you might be powering an auxiliary fan off your radiator, and now you need to figure out how to choose the correctly sized wire for the required amperage.

You need to know how much amperage the fan will draw at maximum speed and the distance from your battery or power point, to the fan’s motor, and then use an appropriate chart to determine the proper wire gauge.

You can find a reliable chart at the 1:37 mark of this video.

Additionally, this video will teach you about electrical relays and the benefits of running them, and how to properly install a single-throw, single-pole relay.

It will also reinforce how different colored wire helps you troubleshoot electrical problems, and the importance of good ground connections.

Lastly, you’ll hear about all of the tools and equipment that can help you more effectively complete your automotive electrical jobs, including multimeters, 12-volt test lights, soldering irons, shrink sleeve tubing for soldered connections, a wire cutter and stripper tool, and a multipack of connectors and terminals to ensure good connections with appropriately sized wires.
