Hi Ya abro964,
Take a look at the wiring diagram for that rack in its manual;
Here is a snip of it;
As you can see, there is no way that LED is going to light unless the fuse is blown.
This breakout board is primary designed to protect the load and module from each other, hence the fuse.
The way you intend to use it is out side the scope of that board…
That said… if you pull the fuse out, it will work just fine.
Wire it as per that doc and you should get what you need.
