You've probably seen this question million times. I am installing a new ceiling fixture in my room where there is already an existing light switch. After inspecting the attic, I discovered that all access to the light switch is blocked off by plywood. I noitced though the wire going to the electrical outlet that is controlled by the switch was accessible. I figured that If I cut this wire then splice them together as well as the new wire to the light fixture, connecting white to white, black to black and green to green would do the trick. I did this the outlet works fine, but the light fixture stays on when the light switch is off. Is there a way I can rectify this without taking out my saw to get to the lightr switch?
