Radio Wiring Diagram for 2003 S1 gu wagon

[Meez]

Hi, just wondering if anyone has a wiring diagram and colour codes for the radio in a 2003 gu wagon, previous owner has tried to swap in a after market radio and butchered all the wiring so I’m just trying to trace everything so I can fix it. Cheers
