What is behind this skirt?

I haven't taken possession of my TRD-OR yet. What is behind the skirts on either side of the engine bay? I'm looking for someplace to mount an aux fuse block with relays. Stolen picture.

I can look this week, but I can tell you that there for sure are options for electrical mounts. I believe I saw one from KC HiLites on IG somewhere. There are probably at least a few other options out there as well.
