I had an old aftermarket deck in my 4000 when I bought it. The power antenna worked when I turned the unit on, and it contracted when I turned the unit off. The new deck I bought, a Pioneer DEH-P470MP, only had one wire to power the antenna (blue/white) while there were 2 wires connected to the antenna (blue, and a blue/white) I decided to connect all three, to see what happened (suggested to me by a car audio store). The antenna now works the way it did before i took out the old deck but for some reason, the antenna is controlled by the headlight switch. Can someone help me out?

Another problem is that the deck wont turn off even when I take my keys out of the ignition. Everything, including the engine, shuts off, but the deck keeps on running until i manually turn it off from the deck. Once again, can someone help me out?
