    I want to attach a permanent connection for my Ctek maintainer. Looking at the battery positive terminal, it looks quite complicated, haha. The big plastic piece with 3 nuts looks like an integrated piece and I’m not sure I want to add my accessories to it. The red arrow nut looks like it should work. Any of you gents have a recommendation? What about the negative?

    Just connect to the jump point under the hood - otherwise you'll need to leave your trunk open while hooked-up. I just prefer a hood up, rather than a trunk open. If you slam the trunk on the charging cable; will you reminder to disconnect before driving off???
