Starters take a lot of power. Just a regular electric switch will not work because the wires have to be so big to handle the high Amp load. When you think of Amps, think of Volume. Think of Volts as pressure. You can have a lot of pressure in a small wire, but it must be contained.
Scion is a sub-brand of Toyota and a niche trade name aimed at young buyers. Founded in 2002, the Scion line is composed entirely of small vehicles powered by four-cylinder engines, with most models priced below $20,000.
Scion (automobile) Scion is a discontinued marque of Toyota that started in 2003. It was designed as an extension of its efforts to appeal towards younger customers. The Scion brand primarily featured sports compact vehicles, a simplified pure price model, and eschewed trim levels in favor of offering a single trim for each vehicle with a range of factory and aftermarket options for buyers to choose from to personalize their vehicle. The Scion name, meaning the descendant of a family or heir, refers both to the brand's cars and their owners.[2] The brand first soft launched in the United States at selected Toyota dealers in the state of California in June 2003, before expanding nationwide by February 2004. In 2010, Scion expanded into Canada.
