I'm scratching my head about what you mean in this question, which traces are you talking about?Also on the photo of the back side, you can see three traces coming from the far right to the pic, the top one of the three is likely enable pin for the 12V switcher, check how that one connects to the pic too. And just to be sure the two others as well.
