The only fuse protection for the purple wire is the main power fusible link that attaches to the starter. I think that is adequate when you consider the purple wire is only hot during engine cranking. If the wire ever failed it would probably be at the starter where high heat over a period of time makes the insulation on the wire brittle and flake off. Same for the red fusible link wire that runs next to the purple wire.
