Fix the Clock
The answer regarding the "live wire" for your CD player is that there are lots of options. But you REALLY need to get a Factory Service Manual or an aftermarket manual with a good wiring diagram. Wiring diagrams are available on this site at:

Or you can go to the Opel Association of North America site and download a wiring diagram. The address is
http://www.opel-na.com/ and there are diagrams for virtually every year of Opel (note: the site appears to be "down" tonight. Anybody know if there is a problem?)
There are a few threads on this site about fixing Opel GT clocks, which a simple search showed up. But the best information regarding Opel clocks is on the classicopels list in the "Files" section under "Technical Information", which has been pretty flaky lately, with addresses that keep on changing. So, I will just copy the information directly here (with a bit of editing), so it is available to this membership:

Hi everybody,
Here is a tip to fix the clock of your Opel (GT) if it has stopped working. Remove the clock from the dash. It is not necessary to lower the steering column and complete dash on a GT. Just screw out all the dash screws and the screws on the left and right side of the bottom of the console. This should give you enough space to get the clock out. Once the clock is out, remove the blue warranty cover which is on one of the housing screws of the clock. You will have to force/break it of with a screwdriver or something alike.
Next remove the three housing screws and remove the white housing from the clock. Taking a look at where the battery wire goes inside the clock, you will see two little eyes, which should be connected with a little wire. The only thing you will find, is the two little eyes with some solder on them, but the wire (a kind of fuse) is gone. That's why the clock is not working. The wire (fuse) burned out. Use a low power soldering iron to solder in a new thin wire in between the two eyes (I use one wire of the core of a regular multi-wire electrical cable). Be careful not to heat up the eyes too much.
After that, hook up a 12 Volt DC source to the clock. Make sure the polarity is correct. Connect the minus cable to the housing and the plus cable to the centre clock connection. At the moment the electrical circuit is closed, you should hear a click. The click winds up the spring in the clock and disconnects the electrical circuit internally. The clock should start working now. If it does not work or just for a couple of seconds, spray some lubricant on all the wheels of the clock and check that the time adjustment knob on the front of the clock is not pushed in (so that it is blocking the clock). Notice that the spring in the clock will not be rewound until it's completely unwound and closes the electrical contact inside the clock again. At that time, current will flow again from the DC source to rewind the spring. This should keep your clock working now.
Have the DC source connected to the clock for about half an hour to see that the clock really keeps working. If convinced, put the housing back on and screw back the three screws, put the clock back in the car, connect the wires and put the instrument panel back in place.
That should be it! I have fixed three clocks now in this way and they are all still working.
Good luck with it!
