Bought a second hand 6 Cd changer - with no instuctions!! Just a comfermation on wires from any one who has fitted one! 1) Ive got a single core blue cable from the changer 6" long - guessing this is the earth 2) ive got a multi core black cable from the changer which splits off into a yellow cable with a fuse 3AMP - Power cable i guess and....... .......A blue plug- with orange, red, brown, blue, green and 3 blacks in it! - straight into back of sat nav, when i get it or standard unit i guess but - whats all the cables for! Changer is a panasonic from a A6, ive got a A4! Also which is the easiest side to run the Amp cable too the boot - id like to run the changer on the opposite side?
