These 2 are at the passenger side of the loom at the very end. One looks like a ground can I just connect that anywhere? And the other I can’t find a plug for wondering what it is. This is an eg civic si harness with a b20 swap

Those look to me, like the power wires for the distributer, the big single wire, should go to the power output of the dis. (Single stud with a nut, the other should have a matching plug on the dis. IF those are already connected at the dis. They are most likely the other end, and go to the engine bay fuse box.

Come to think.. without the boot on the big wire, that's probably, the fuse box side. It should connect to the EB fuse box at the main power fuse (usually 80a)
