These days there are usually two wires that need Power..
in a CD player or even late model tape players..
The Power to Play CDs usually goes to the ignition On Fuses which are the first two fuses on the left [when sitting in the drivers seat]
The Second Power wire needs power all the time for the memory & clock etc.. which would go to the last fuse on the Right Hand side.....
OR
if You would like to have the music playing with the engine Off as I do, then You would connect both wires to the last fuse on the Right Hand Side [No 10].....
and You would use the On/Off switch on the CD Player....
You can buy extra wire from Dick Smiths or Jaycar or any Hi Fi Shop.... You May run into problems if You also install an AMPLIFIER ... which I believe aren't really needed if You have a good CD Player with 30-50 watts of [rms] Power.... plus You won't need large speaker wires etc....
