Audio Wiring Diagram/Help

Hey Guys.

Could anyone help. I have been looking on here and Google but not found anything that can help me yet.
Basically the previous owner of my A3 decided to cut off all the ISO connectors for some god knows reason! Because of this I simply just have a load of cut wires where my head unit is going to go. Do any of you have a diagram that explains what wires are what? IE The colour of them and what they do etc.
Also it would be great if anyone had a ISO connector guide so I know what ones I should put into what socket on the ISO.

Thanks guys.

I had this on mine and it was a right pain to sort out.

Do you have Bose or standard setup? Are you trying to put an Audi or aftermarket head unit in?

Its the standard setup and trying to install a Sony Aftermarket.

Best bet is to go to a scrapyard and try and find the same model a3 as yours and cut the connectors, then you can solder them onto yours.

Yeah I thought that maybe the best way :S
