205 Junior Cd Player Wiring...

I have just bought a peugeot 205 junior and then a relative bought me a cd player for my birthday. I took out the old radio, cassette player, which wasnt connected at all, and I found these wires...

I know the 2 yellow and the 2 beige wires are for the speakers, and the large blue wire is the arial. But the rest are a mystery to me. Any help that anyone can give me about which wires are what will be a great help. As I am hoping to wire it all to an ISO adapter. Thanks.
