So I watched this video of someone modding their LED. What she did was she removed the controller port where the LED was located and de-soldered the old LED and replaced it with the new color. The question I wanted to ask before I start doing this myself is where am I going to connect the negative lead? My assumption is that I solder it to one of the soldered points on the board since it just needs to be grounded. I have no history with soldering or an understanding of how electronics work so please do tell me if what I am thinking about doing is wrong.
