That's why I said switch and not relay!
(Not that it's really the right way to do it - but I can't see how to do it otherwise - sure doesn't look to ME like there is ANY stereo input at all.)
HEY, I have heard of a CD changer being available from the factory. How does THAT interface? Is it a whole different head? Must be - where would it go?
(Just wondering if some of the pins on the TOP connector would be for that...?)
