Headlight relay system and Convertible top relay system recommendation

Thanks to FABO.
The only missing piece is how to determine the length of the fusible link on the alternator charge wire?
60 amp alternator, 8 ga wire, not sure exactly how long if a run it is.

I have a 50 amp maxi fuse with an 8 ga, 60 amp holder I was going to use but I don't think it is the correct size. There are hundreds of opinions on maxi fuse/wire gauge size, and 1 confusing article on fusible link length I was able to find.

I'd use a 12ga fusible link that is ~6" long.
