It looks like you’re missing the right side of the brake light fuse. You can get the right side “clips” and they will just push in, then get a fuse. I don’t remember if the brake light wire is behind the fuse block or if it comes off the end, but no fuse means no power. The left side of the fuses should all have power - depending on if they are switched or unswitched. I’d definitely clean up the crust on the fuse clips, then start poking around with a multimeter or test light to confirm 12v. The fuse boxes are pretty straight forward, so if you can find some pics of other similar year trucks, you can see what is connected.
