I am putting in a 2nd Gen b16 into a 90 Civic Si. I have a 2nd gen motor with a 1st gen cable tranny. I also have the OBD-1(gray plug) engine harness that came with the engine. I need to know which dash harness will be best for this swap. I know there is no one harness that will work, it will have to be a hybrid harness, since I am converting a non-OBD(white plug) car into a OBD-1 car. And NO, I don't want to use 1st gen injectors and distributor! I know that will work, but it won't pass the SMOG REF. If I change it to OBD-1, I can smog it as a Del Sol. I think the harness from 92-93 Integra might work, with minor modifications. That is probably the best bet. I am talking about the harness that plugs into the ECU and goes through the firewall to connect to the engine harness. I think a OBD-1 harness form a Civic or Integra might work also. Has anyone done this before? I you have, let me know which dash/ECU harness you used. Any help will be greatly appreciated. Thanks.....
