1 - What exactly does "the new one" refer to? The switch, receptacle, light fixture, or all 3? What did you change?
2 - If I am reading your post correctly, the light fixture plugs into a receptacle and isn't hard wired. Or are you talking about a different fixture than the sconce?
3 - Before you changed anything, was the top half of the receptacle unswitched and the bottom half switched?
4 - Turn off the power, remove the switch and receptacle. Undo all connections and seperate all the wires, and write down how many sets of wires each box contains and what color wires belong to each set (eg switch box - 2 sets - set 1 - black, white, bare - set 2 - black, red, white, bare). Post the results.
5 - If you have a meter and feel comfortable doing so, turn the power back on and test to find the feed by touching the bare ground with one probe and each of the other wires for the corresponding set with the other probe. When done, shut the power back off and cap each wire with a wirenut.
