Edited Raster Graphics 5)

Got heaps of different versions of this plug/socket ...but i decided to stick with this one as it looks best.

First of all I used burn and dodge tools on the plug and the side of the socket. Then i used the cutout filter. I then imported the layer from a previous attempt, which was the plug and wire, but changed the effect of them. I added in a rectangular box(just the outline) and used an effect to create the outline for the socket.

Also used skew to fix the shape of the image and make it straighter than it was.
