On my new Mac Mini 2018, I watched a youtube video and read ifixit, but I messed up when removing the LED Indicator connection and I broke the connection off the board. Big ooops! Best I can tell, the only thing effected is the light on the front. I can live without the light, but I wanted to make sure I didn't mess up anything more important. The computer seems to be fine without the connection but I have in powered down in fear of messing anything else up.
