So if I am going to ground pin 30 on my computer is it safe to just strip back some wire on the wire comeing off pin 30 and connct a ground wire there or should I use a paperclip and put wire on it and shove the paperclip into the back of the harness on pin 30? Also is the harness numbered or does anyone know what color wire is on pin 30? 89LX /A9L
