There is a yel/wht wire that goes from the radio to the automatic antenna. When it sees voltage, the antenna goes up. When the voltage is absent, the antenna goes down, or at least it is supposed to. Lighting/dimming comes in on the red/blk. Power comes in on the yel/red, freek memory comes in on the wht/yel and has power all the time even when the key is off. Hope this helps. Did it work properly before the new radio was installed? If so, take it back and make them fix it.
