Hmm looking at the location Radio? you have the positive and negative and then you have the wire for the light bulb.. But there is a good chance I am wrong.
the blue with red stripe should get power when the lights are on. dont know what the white is for. it could very well be for the stereo. by the way. the stock stereo grounds through its case not to a wire.
