are you talking about the wires going to the plug in the back of the sony? or the factory plug? And what color wires ARE present? FYI if in doubt you can always cap/tape off the illumination and/or dimmer wires and still use almost all of the features of the radio.

Thanks for the help. this kina helps, Ineed the sony plug wires. Its missing most of them. so I dont know where they go. I figured out +,-,AMP,and acc. I wanted to find the ILL because its really dim in the day. I knowsome units run off the dimmer in the day. Thanks. this is a start.

Most Sony's also have a dimmer feature in the menu. 3 settings, AUTO, ON, and OFF. This bypasses the vehicle lighting dimmer and uses Sony presets. Check to see if you have this feature.
