This is located in the 99-04 model behind the rear seats in the middle under the rear deck lid. I am not for sure of the colors right now, but I will look in the moring. To make a long story short hook in to that and that is your remote wire. Next you will need a box that changes your rear speaker wires (also found in the same location as the remote wire) to rca jacks. You can get these at walmart I believe. Next hook everything up to your amp and rock out. It is simpler than it seems, but if your not to sure about it may be best to let a professional do it. I'll try to get those colors of the wires to you tomorrow.
