I need to wire this JDM obd2 b18c5 into my obd1 94 Civic Si. I have not been able to find much usefull info on how to do this yet and the motor is due to be here early next week. I would like to know what is the best ECU/OBD set up and how to handle the wiring. Is it worth while to go with the AEM stand alone engine managment system or somthing like it. Thank you in advance for your time.
