A nitrous oxide plate system having a plate adapted to fit in an intake pathway of an internal combustion engine. A method of making a cable including forming a conductor bundle by placing helically positioned conductors and optical fibers about the periphery of a central optical fiber or metallic conductor, encasing the conductors, optical fibers, in a polymeric insulation material, and grouping the conductor bundles together. When the first internal signal 104 goes high, a flip-flop 1 reduces the level of an in-phase signal 103 to low, and increases the level of an antiphase signal 102 to high.
