I was looking at my wiring diagram for my 69 camaro. I am running a positive wire from the battery to the junction block. Do I run it directly to the junction block or do I need to use a fuse. If I need to run a fuse, what size should I use?

My '68 calls for a 14 gauge fuseable link which is basically a wire that "acts" like a fuse.

If you use the repro spring ring cables, they have the correct fusible link and termials as well.
