I recently installed the Viking chip as the "Duo" setup. I followed the diagram and connected all the points the best I could. Now I tried to see if the controller would power on buy just hooking up the PNC cable. The cable light is green but the controller wont turn on when I press the Xbox guide button. Do you think that it could be a grounding issue as far as where the chip is placed? I cant really trouble shoot the issue because the controller isn't lighting up at all.
