Grats on the thread revival. And The power antenna works off the power antenna wire. And my auto antenna works great. Never once has it malfunctioned or made really any kind of noise out of the ordinary. I would suggest using the antenna untill it does break then the soft antenna mod is the way to go. But for the antenna wire it is a blue wire with a white line on it if im not mistaken. if it is not that wire. give me like a hour and ill tell you exactly what one it is. That is if you even need this info anymore since it is half a year old.
