Hey guys, as the title says, I'm new to rx7s, and working on cars in general, but I'm very interested in it and the automotive world, so I picked up my first project today, a 1993 rx7. I could use your help identifying a few parts, some of them I've figured out, like the o2 sensor and a couple relay boxes, but there's a bracket I have no idea about. Ill attach pictures of everything and you guys can feel free to point out anything you recognize. Any help would be much appreciated.

There's also I black bracket with holes in it I don't have a picture of, bad description but maybe someone will know.

That's the underside bracket the FD has 3 of the in total, all a lil different from each other.
