Wire sizes will vary depending upon what they are hooked to. Example, #10 is generally used for the alternator, #14 for gauges and such. I suggest you do a search for a typical wiring harness. Another thing I suggest is to use the correct wire size WITH the correct type of insulation. Not all insulation is suitable for the heat and organic fluids (oils & gas) around an engine deck.
