Go to
Radio Shack (You've got questions, we've got blank stares!).
Get p/n 274-710 (its called a "Car Radio Plug" - who've thought?) and p/n 274-384 (or the like).
Connect them with some wire. Not sure how critical shielding is in this app.
Plug one end into the end of your antenna wire, and the other end into a DSB-R100 or other FM tuner w/RCA jack for the antenna. I'll leave it as an exercise for the reader to determine which end goes where.
Fire up a radio tuner app and listen to your radio.
The end.
