Factory fused extra power source

While installing a towing brake controller, I found a fuse slot I could use so I wouldn't have extra fuse holders hanging around.

The plug is on the backside of the fuse panel. It's the only one with a bail that locks the plug in place. I had some extra harness where I found the right terminal to put in the connector. Yeah some extra work but made for a cleaner instal. Would be a nice connection for an amp, CB, or whatever else. I would like to add that you need to disconnect the battery when you remove this plug. Some of the connections are for the airbag system on that connector. As you can see in the middle/yellow part of the connector.
