The electric resistance is reduced, and the efficiency of the engine and the electric component is improved by allowing the dedicated wiring from the effective point to establish a ground for the electric current that normally returns to the battery via the steel plate of the body.  A wire that contains as many as 1522 oxygen-free copper (OFC) cables that are low in resistance is adopted as a material.
