Huh. Those blankety-blanks went and changed the color coding after '93, then, because I just got through checking the '93 manual.
For '93, the antenna signal wire coming out of the stereo is indeed pink. It leads to the antenna relay, which is mounted on the antenna shaft in the trunk. That relay has an orange always-hot power supply to feed the antenna motor, the pink signal wire coming from the stereo, and a ground.
There are three wires leading to the antenna motor: as you noted, they're white, green and dark gray. The gray wire powers the antenna up; the white powers it down; the green is a common return (but technically not a ground as I believe it leads back to the relay, not to the body).
So anyway, your pink wire can signal the amplifier to switch on (i.e. close a relay to switch on its main power), and your orange wire can power it if it won't suck too much juice; run your own power circuit to the amplifier otherwise.
