Fusible link ????

The one that hooks to the starter relay. I didn’t cut the old one off and he doesn’t remember.

I thought there was only 1 FL. I could be wrong though.

And we moved the battery to the trunk and did the ammeter bypass so I’m ASSuming it goes into the wire that now feeds the system.
It depends on what the vehicle is. The later ones, like 73 and up started havin more lecktrik junk on um and I've seen more than one. S'why I asked. I agree on the length. I'd think 6" would be about the max. Just cut a length twice the length of your little dingy and that'll be it. lol
