Hi there, I am trying to fit a new radio in my 1999 Mercedes Sprinter 308D van (after someone broke in & stole the old one!!!)

These are the wires coming from the dash. Can anyone tell which is what?

1. Black with Red trace
2. Black #1 (thick wire)
3. Black #2 (thin wire)
4. Brown with Green trace
5. Brown with Red trace
6. Brown #1
7. Brown #2
8. Green with Grey trace (& Red spots)
9. Red with Yellow trace
