if you have emmisions testing in your area it may be a concern.. they plug into the ALDL port for OBDII cars to test the system it will read"no communacation with PCM" causing you to fail. your best bet is to change the timing cover to a 96/97 and get a 96/97 engine harness and pcm that will also include rear o2s,you will also need to change your icm as well cause the plug is different. it will be well worth the swap in the end.
