1997 Mitsubishi Eclipse CD player wires

Ok so, I am trying to hook up a new cd player in my eclipse and the guy who had to car before me cut off the cd player adapter and wired every wire individually. So I got an adapter not knowing he cut the part that that connects to off. And the wires are color coated differently from my new cd player wires so I was wondering is there somewhere on the internet I can go to see what wires go to what speakers and battery and stuff.
