I wired my Sony D7 Discman directly into the Toyota radio in my '83
Supra.

Inside the dash, there was a 9 pin din connector between the
radio/cassete player and the equalizer.  (This is in addition to the 3
pairs of molex connectors.)  It turns out that the cable caries two
pairs of stereo signals to the equalizer (flat and tone-controlled) and
1 back from the equalizer.  I put a DPDT switch in that selectively fed my
discplayers line out signal as the flat input, instead of the radio.
The switch, the disc player, and some padding, fit into the glove compartment.

It was easy to do and it sounds fine, except that I have to pop in a
blank tape (really an empty cassette shell) to turn off the receiver
portion of the radio.  Even though the switch disconnects the radio's
output, somehow the radio bleeds through at a low but annoying level.  I
couldn't find a less kludgy way of keeping the amplifier on but the
radio off, since they are so well "integrated".

You can get schematics for Toyota Radios (or at least for Fujitsu Ten
radios) from United Radio in New York, (315) 446-5570.  If you happen to
have the same one as me (on the front panel it says tuner 1622, graphic
equalizer 1701), I can give you the pinouts you need.
