Hi, Thanks for your question, without seeing the vehicle, it is difficult to assess as fitting parts for an after market stereo only start from 1998/99. It may be the case that the KDC-200UB is a straight fit with an ISO harness & aerial adapter. We have shown parts below but these ARE later year parts.
