pioneer deh 3000

[Kaleb Knauff]

I have a pioneer deh3000 car cr player, with cd changer controls. I was
wounderig if any one knows the pinouts for this. so that I could input
sound from some other source (mp3, tape, etc.) I don't care if I can't
control any of the fuctions. just want it to play throught the stereo.

thanks
