Hi Josette, the problem you have is to pass the cables to abitacle right? You lift the capo and the right under the clean there as a plastic rejillita, which goes from end to end, hitting the glass, because under that rack, you have to look good, to the right near the fin (it seems to me) there a cable surrounded by a gum, there you have to pass the cables, be careful with the joint pq but put it on it or the break will pass. To the light button, in short I hope you find it, a greeting
