Radio Wiring

I need some advice for the wiring of my new car stereo (Sony).
WhenI first got the car, it had a defunct Blaupunkt radio/cassette player. The car plug was long gone. The Blaupunkt only connected with loose wires straight to the radio.

I purchased an original Craig radio from DMC Houston, and thanks to Ralf Philipp in Germany I was able to figure out what wires went were. Also, the car wiring was cut and some wires missing (at least they did not correspond to the colors!)so I had to get a car plug from DMC Houston in order to hook everything up to the Craig radio plug.

But: It wasn't easy as some of the wires had been changed or removed completely like I said. I hadto use a plastic "cube" or "bridge" connector (the ones you put wires in horizontally and fasten them with screws on top)in order to connect the loose wires from behind the center console. Anyway, I got it hooked up and working. Loose wires to the car plug and from there to the radio plug.

Finally, I got tired of the Craig radio and wanted a CD-player in the car. To make things easy I bought an standard ISO-pin connector for the car together with the Sony which I believed would be fine.

Now here's the problem I've come across:

There is only one red wire going into the "cube" and two wires going out of it (red and orange)towards the old car plug. Looking at the colors I realize that the two wires are the +12V line AND the ignition-switched +12V line. But they have been fed by just one wire (the red one) Is this supposed to be this way?

How can this be? I mean, it has worked when I hooked upthe old Craig, but I doubt it will work with the ISO connector which have 2 wires, one for the 12V and one for the ignition-switched 12V line.

The red and orange wires also have the inline fuses, should I keep them?
The sony player has an built-in fuse (10Amp)

>Power supply:
>+12V (continuous)    red
>+12V (switched)       orange
>GND                              black

>The (original) wire colors IN THE CAR was supposed to be:
>
>purple for the +12V (continuous), fused with 5A cable-fuse
>green/white for the +12V (switched), fused with 5A cable-fuse
>black for the supply-GND

Now, neither the purple nor the green/white wires are there. Only one red wire which I connected to the cube, and from there connected the red and orange wire coming from the car plug.

I guess I could leave the red wire connected to the cube and cut the wires after the inline fuses, but the main problem remains - Are the 12V and 12V ignition supposed to be on the same wire? Or am I missing completely the 12V ignition wire?

Please help!
