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???
I’ve connected my CTEK quick-connect at the underhood fuse box, just leave the hood ajar when charging: Video #23 here, by @NutzAboutBolts, shows how to access the 12 volt positive feed-in point at the fuse box. The CTEK connector has a robust plastic shoulder, and there’s limited space at the fuse box connection point, so I had to trim off that shoulder, bend the ring connector through a sharp 90 degrees, to fit. I found an unused threaded hole just a little forward and down, on the car body, connected the CTEK’s neg wire there: I have a few spare small metric bolts though, believe it’s 6 mm thd diameter (10mm head). Without an extra bolt, any existing body bolts should work, verify with continuity meter.
