Adding third stall on garage

[chumleyrc]

I have added a third stall on to my 2 car garage. The original garage had one light in it up front. Out of that light another wire went over to the outdoor light by the service door. When I took down the outer wall that that light was on I put that wire up in the rafters with the thought that I could use it to tie the other lights that I would be putting in the garage. When I did this all the lights work, but the switch does not turn all the lights off just the original one that was in the garage. I am at a loss on what to do at this point. I would appreciate any help.

Te wire that you put in the rafters is a hot leg, not a switch leg. You may be able to change that at the interior garage light switch location.

Evidently you don't have the wire that comes out of the original switched light

Turn off the power, open up the original light to get at the electrical connections.

Figure out which wire is the one going to the other lights. You'll probably find that the black lead from this wire is connected to a red lead that goes back toward the switch. Disconnect this black lead from the red lead, and wire nut it together with the other two black wires in the light.

Wire nut and apply several layers of tape to the red wire. Put the original light back together.

Turn the power back on. All the lights should work from the switch now.

Now turn the power back off. Take the cover off the switch. You will find that the other end of the red wire is connected to one black wire that goes to the switch. It may be wire nutted together with the black wire, and another short piece of wire that goes to the switch, or it may be doubled-up on the screw on the switch. Either way, disconnect the red wire, put a wire nut on it, and tape it off with several layers of electrical tape. Put everything back and turn the power on.
