Stereo & Electronics - Help! Cd Changer wiring -Orange wire goes?

I am trying to fix a mess in one of my friends cars. We are putting everything back stock. We have the plug in wires for the back of the headunit and the blug in on the back of the changer but it will not power up. We matched up the wires color to color but there is an orange wire left over coming off the back of the changer. Where does that wire go? Apparantly we are getting no power to the changer itself. Help on a Saturday afternnon project appreciated!

The orange wire normally goes to the RADIO ACCY fuse but any constant (battery) power supply will work.
