Hello all I am new to the forum but belong to several others with my other cars and always get great advise so I would imagine I would find the same helpful knowledge here. I have an 07 A4 with Symphony sound. I am trying to install a Pioneer AVH-P2300 head unit. I purchased the wire harness kit and wired everything as per the instructions but when I install the unit I have no rear speakers. I figured out the rear speakers are powered by a seperate amp and wired into the OE unit through the green plug but on the new harness there is no connection for that plug. Can anyone tell me how I should attach the wires from that plug to the new head unit. I am guessing I need to cut and splice the wires but does anyone know what wire goes where.
Thanks
Mike

 

I had this issue with my 99 awhile back does your new wiring harness have two plugs? The one I have has two because I also have the bose and if you have the right harness that green plug is supposed to fit into the second piece once I wired up everything correctly my back speakers finally worked ill try and see if I can find it but I went to weebee audio and video and they had the harness I needed
