i've just purchased a seat arosa 04 however having issues with the head unit the previous owner butchered the old original plug so pretty much left with the wires that i need to match to an oem iso plug i'm unsure what wires i need to use. i have the following.
thick red
thick brown
black
green/ white
grey/ white
blue/ grey
red/ brown
also does anyone know the locations for the stereo fuse so i can check that as well
