Wiring the C10 with Amazon Relay distribution box for the LS swap conversion

The C10 was picked up with a lot of wiring still required for the truck to start. My LS Harness doesn't have the fuse boxes or relays, so I ordered one from Amazon. Keep in mind this is not said to be a better option than stock or anything, but it is definitely one that should work for me. The brand of the Distribution box is True Mod, I provided a link to the seller whom I purchased mine from below.

It’s coming out nice but? What bracket are those if you don’t mind sharing.
