Yes it turns off with the car (the one in the centre console does - U guys get an extra in the little compartment between the seats, we don't have that one, so I can't tell...but I guess it goes off too).
Just reconnect the wire to the cable coming to the ignition lock from the fuse box. This way you can load a lot on it be4 the fuse blows...
I don't have such a pic, and I'm not planning to disassemble my car in the near future, but it wouldn't be hard to find after removing the front (as Javah described so fine in the thread about the stereo install).
BTW: Where did HE go??? Hope he didn't crash his 6 in a Finnish Pine and end up in hospital...:sarc
