Boom Vader taillight/brake light not working

[Notshaw]

So I just finished installing a fender delete kit, and found out my brake/ taillight was no longer working. I’m not exactly sure it was working before I started but all I did was unplug the harness so what could’ve gone wrong? Any ideas or help is greatly appreciated.

If you touched the HOT lead to ground, you can pop the fuse in a fraction of a second. If you disconnected the harness, anything that used those conductors won't work, duh.
What did you disconnect? Are you sure you plugged things back together tightly? Are the connectors you did reconnect in the proper plugs, or could the plugs be crossed? Many bikes have 3 wires for ground/tail/brake lights, and then 2 pairs of wires for turn signals. If you touch them as above you can blow the fuse, and if you connect impropely, they won't work as designed.
