    it is illegal to convert a car to a previous OBD
    depending on where you are located you could end up with a car that is no longer road legal

    the plugs for the injectors, distributor, and alternator are different between OBD-1 and OBD-2
    swapping those plugs or parts will have you good ont he engine harness side

    you will (may) also need to lengthen a few wires to reach on the B series

    then you will need a conversion harness to plug in the OBD-1 ECU to the OBD-2 ECU harness in the car

    but as i said if your state has or ever gets emissions testing you are fucked

    1. Reuse your injectors (they're the same CC) or just remove the blue piece from the inside of your OBD2 injector plug and the B18's injector will fit
    2. Swap the internals from your old distributor into your new one or get a distributor adapter harness or get an OBD2 distributor from a DOHC VTEC B-series engine
    3. You can swap the plug off your D series alternator and bolt it onto the B series alternator.
    4. Wire up the IAB's
