Whats up guys I'm trying to put my JBL system into my Taurus today. I got everything put together but I noticed on the sub harness there is a little grey plug connector with a single red wire on it that doesnt plug into anything in my trunk. When I was removing the harness from the car at the junkyard I remember unplugging it but I didn't think that my car wouldnt have it. I'm assuming its a power wire because I now have no sound coming from the rear speakers or the newly installed subwoofer. I've searched all throughout my trunk and cant find anything it would plug into. My car is an optionless Taurus LX. If anyone could tell me what exactly that is for or if I have to go back to the junkyard to get the other end of the plug or what i need to do I would appreicate it. Thanks.
