I attached a flat metal strap bracket to the terminal block’s 2 uppermost mounting holes. That bracket is bolted to bike via the battery’s hold-down bracket bolt. There were no clearance problems between the terminal block, the underside pan or lower edge of seat, or the upper edge of the body side cover, at all.
The horizontal central “hump” of the 2 metal jumper clips can be seen between upper & lower terminal screws.
The little ring terminal jumper wire that connects the left and right terminal rows is connected to the two lowermost terminal screws, and tucked inward between the bottom of the ground block and the top of the battery casing. Bearing in mind Fred H’s admonishment to not use too thin a wire for the primary connection, I went a little bit on the “overkill” side and used a 10-gauge wire for the primary connection between the negative battery terminal and the common ground block.
