I bought a track light (with a dimmer) which I would like to connect to the existing recessed light to brighten up a wall. The track light has a normal power plug. Is it possible just to cut the power plug and connect the cables with the recessed light? And if so I have a black and a white cable and the ground on the recessed light and two cables on the power plug. Which cable should I connect with which?

With the link you can find some pictures of the recessed light and the track lighting.
