What wires have you got behind your stereo? You should have a permanent live(memory to store radio presets)a switched live(off the ignition) and another switched live off your lights(illumination) these are usually red orange and yellow. What make is your stereo and I'll have a look and see which should be which according to manufacturer as they sometimes have the permanent and ignition lives the wrong way round but you can come off the ignition live as long as you fit an in-line fuse. The best option may be to get another harness for your stereo - you should be able to pick one up cheap enough on eBay.
