yeah, what Cletis says, you don't want to make everything the same color and gauge or you'll never be able to trouble shoot anything .... circuits are usually different gauges, from 16 to 10, depending on how much current they're expected to handle - assuming there's enough left of the originals, you should be able to tell which needs heavier or lighter, and most any auto or hardware store will have rolls 12' to 25' of at least half a dozen colors in different gauges - lighter gauge wire will be cheaper and fine for things like ignition and small lights, the more expensive heavier gauge is useful for the charging circuit, horn and headlights
