In order for your automotive electrical system to perform properly, your wire must be sized properly based on the amount of current (amperage) the wire must carry, and the length that the wire needs to be. For example, you want to add some flood lights to your vehicle. The floodlights draw 15 amps of current. The length the wire needs to be to connect to the floodlights is 9 ft. Based on the chart above, you would want to use 12 gauge automotive wire for your floodlights.
