You can get the harness at just about any car audio dealer also. If they carry METRA brand then it will be a 70-1720T. The factory radio also keeps the dome light working. Like it was said before the only Civics it affected is the 96-99 models. You can stash the radio behind the part of the console where the cigarette lighter is. You may have to move some wires over behind there for it to fit properly but it will go. Also when you put the radio behind there you will need to make sure that you have the part of the radio that has a "gap" or "empty space" in it which is the top of the radio where the tape player would normally go if it was in the head unit, facing out toward the cigarette lighter. It will need to be this way so that the cigarette lighter can fit in that space. Good luck.
