I have been searching old posts, but can't get find an answer to this particular problem. i also can't find anyone in the 04-06 board that knows this. I have the single cd player and am upgrading to the audiophile. I have the sub connector wrapped to the harness under the dash behind the radio. But... I had the entire sill plate off the drivers side and the rear piller trim off and can't find the end under that should be under the rear seat. Has anyone else had the same problem? There has to be two ends to a wire right? Does anyone have the diagrams showing where exactly this connector branches off and where it might be wrapped up? Thanks all!
