Question:

Are there any internal fuses that would cause this to not work? no power at the 4 plug? I know there is an inline fuse where it connects to the battery. I have a 2001 Tundra SR5 4wd, brake lights and turn signals on the truck work normally, but not getting any power at the 4 plug connector?

The only fuse of the Curt trailer wiring kit part # C55738 is in the red fuse holder you referenced. Most likely if your fuse is good but it's still not working the problem is the converter box. You can test this with a circuit tester like # PTW2993. If there is voltage on the input side of the box when taillight circuits are applied but none on output side the converter box is fried and is in need of replacing the entire kit since they are not available separately.
