First RTFM from website (don't bother with youtube videos). It will show you the points you need to solder. Second, the trigger points and pins on the power/sync points are very close to the other pins, if you are new to soldering be aware that this is not like replacing a potentiometer module. Everything is explained on the page in the instructions. I can't say MANUAL enough, you should read it. No issues with my controller, it works as intended and the mod options work as well. Total installation time was about 20 minutes.
