So I recently installed a pioneer avh p3200 everything went well untill I tryed to put the stock stereo back in. I think I'm missing the wire that goes from the back of the stereo to the hot and cold twist control. I might of lost it or maybe I'm doin something wrong when I put it back. Please help anyone! And one other question will the metra kit come with all the wires to install it and hopefully fix this?
