Even without a wiring diagram in front of me, I can tell you that the green wire is probably _not_ a ground; that color code applies to household wiring but not automotive. (99% of the time, black is ground on a GM car, but even then there are exceptions.) The power antenna is bolted to the body already, so its chassis is already grounded.
I believe you may be looking at a signal wire from the stereo and power supply wires to a relay that will power the antenna (in one direction or the other; the power supply wires may reverse polarity depending on direction of antenna travel). In any event, wait for somebody with a wiring diagram to jump in here and give you specifics (hello, Fuddy?). Also, if you haven't got a test meter or 12V test probe light, now would be as good a time as any to get one.
Hang on; it shouldn't take too long to resolve this...
