It tightens and loosens just fine. The nut simply doesn’t come off the bolt. It’s pressed on from the factory so it doesn’t get lost. I’m thinking about just running a bolt through the hole to the left of it and running a new ground from there. It’s a one piece brass clamp so it’s still ground. Ground is ground no matter what part of the clamp I secure another ground wire to.
I’m not worried about the bolt. What about the molex type plug that’s the wire to the left of the battery post? There are two 16 gauge wires attached to that plug, which is some sort of battery sensor on the negative side. How would I attach that to a new clamp?
Seems like lot of work when you could cut the bolt off (a lot easier than trying to go through, it, trust me). The nice thing about the t-spec distro is that it comes with the add-on post so you can use the existing connections too. Just bolt them on, use the additinal holes for whatever additnal grounds you need. That or just use that existing hole I see there, buy something like this off amazon:
With the t-spec distro, you don't have to change any of the original terminations. Just loosen the bolt on the factory unit shown, pull off the entire assembly, clamp the t-spec on, tighten it's allen bolt clamp, screw on the extra post that it comes with (it comes with the mounting screws too), in whichever hole works for you(that's what she said) Once that is re-connected, you can run any new grounding like multiple 4awg or multiple 1/0 gauge upgrade cables in the remaing receptacles using a standard allen wrench. The T-spec has an allen bolt in each of the receptacles you see i that picture.
