if any of you are using harnesses instead of seat belts and have those horrible seat belt things in the door and want to remove them it uses a e40 size star pattern bit on the top and after removing the seat belt thing there is four wires running through the door gound the green one to the door and you car won't know that the seat belt thing is missing. it's really annoying driving for two days with that **** going off the whole time. even though the song of the 8000+rpm will drown it out alittle.
