I am trying to purchase an aftermarket CD player for my IS, however nobody seems to make a wiring harness for the radio?? I was told by Crutchfield that they have the color of wires I am supposed to splice into but I don't want to buy from them, they are about $130 more on the CD player I want than the local stereo shop here, but of course I want to install it myself? Can anyone help me on this?
