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.
