I've just bought a MK5 Golf, but unfortunately the previous owner was deaf, so he didn't order the radio preparation when he ordered this car. I didn't realize this until I wanted to install a radio in the car...

I'm looking for the wiring diagram of the original wiring loom of a mk5 Golf. I'm not looking for the pinout of the quadlock connector because I already have that.
The most important things I need to know is where the wires normally are connected, and if the constant +12v is directly hooked up to the car battery, or if it runs through a fuse first, and if it runs through a fuse, then I also need to know which fuse.
