Checked all the fuses and they are all fine, my cig lighter dont work but i think thats a faulty unit?

can anyone tell me what colour the wires for the radio are because on the loom for my cd player it has things like illumination etc and i have no idea where to plug all this.

Im still struggling to find out why the clock and fuel guage have stopped working but the light behind them works its very weird i tried re-seating the round cable going into the clock but that didnt work.
