96+ is OBD2
95- is OBD1
If you get an OBD2 ECU, it'll plug right into your car (if you have a 96+). If you want to go with an OBD1 ECU, you'll have to put the adapter on your ECU harness to get it to plug into the OBD1 ECU. 
96+ won't plus right up...
96-98 will plug into a obd2a harness
99-00 will plug into a obd2b harness
They made minor changes in the ecu in 99-00. They changed the plugs from ABD to ABC.
