This is all you need is a ECU adapter...OBD0 to OBD1 ECU Adapter. Allows the use of an OBD1 ECU (92-95 Civic/Integra/Prelude) in a 88-91 Civic/CRX/Integra. Add the OBD0-1 Distributor Adapter so that you do not have to cut and splice your distributor plugs! Add the Engine Subharness and all of the extra wiring will be done for you! (VTEC Solenoid, VTEC Oil Pressure, 4 Wire Oxygen Sensor, and Knock Sensor!) Add both the Distributor Adapter AND the Engine Subharness and the conversion from OBD0 to OBD1 will be SIMPLE and EFFORTLESS!
