The
ebay cables can connect an iPod, or both iPod & AUX MP3.
The lower left plug is the iPod/AUX input. The heavy plugs on the right are speakers. The plug on the left is the steering wheel control. The second from left is the 6-disc player input (if you have one or want one). I have heard this may also be the input location for the Serius or XM equipment.
