My trsty old '91 legacy finally went the way of all flesh, and, Subaru
fanatic that I am, I managed to pick up a spry little '98 Legacy
Outback Limited.

It's got most of the bells and whistles, which is cool, but the one
feature I loved the most about my old '91 isn't present on the newer
model: a line-input jack on the radio.

I was wondering if anyone had some wisdom as to how to install one on
my own. From what I've managed to google, the hookup for the optional
CD changer is the way to go, but nothign I've found was particularly
long on details as to how to do this -- or even where exactly that
hookup is.  Even the Haynes manual I bought for it doesn't have
anything even remorely resembling the details for the radio wiring.

(And while I'm on the subject, is the CD/radio/cassette deck supposed
to have any illumination? I suspect mine fell victim to a former owner
who wasn't comfortable with the location of the cupholders -- so any
suggestions as to whether this is reparable damage, or, failing that,
recommendations for a replacement unit)

Thanks.
