I was under the impression that there were left+ left- right+ right- in addition to the serial lines running from the CD changer to the head unit. Is this not the case? Thanks for the help. Barry

I am looking to wire my XM radio Roady 2 head unit directly into my ES300 "premium stereo". I am using the FM modulator now and I'm not really too happy with the result. I do not want to use the cassette adaptor either. I figure that I can tap into my CD changer input/output and add a hookup for my XM through that. I would like to find the male and female wiring harness plugs that connect the CD changer to the radio head unit and build a switch so I can switch between the two outputs. Does anyone know the part number for both sides of the harness? Also, where is a good place to get them? Thanks, Barry
