Why does the safety trim kit have two wires for everything? Going to the Servo motor I have 2 20awg wires supposed to hook up to a single 22 awg wire. Is there an advantage for this? What is the best way to butt slice two larger wires to one small?

Also, the kitfox wiring schematic has two 14awg wires from the alternator. Does it need it for load reasons and if so why not use a larger wire? Is it for redundancy? Is it really necessary?
