    h22a4 swap help

    Ok i need help I am swapping a h22a4 into a 96 accord so what I am wanting to know is can anyone help me get this right. So i know that I cant use the stock prelude ecu on that. But what i want to know is that the motor is obd2b and my car is obd2a the injector plugs arent the same. So I am palnning on swapping to obd1. So anything would help and I know about cd5tuner but i havent been getting alot of help over there.

    ok let me clear this up for him

    Car: 96 accord coupe is obd2a and has a resistor box (which is why we are going to use the obd1 injectors also because the obd2b (lude injectors wont plug in)

    Motor: h22a4 do we use an internal or external coil dizzy?

    also weve read things about a potential problem with the crank sensor being on the crank side of the motor (h22a4) vs inside the dizzy like on my h22a1.

    i have done an h22a1 swap in a cb7 myself but his is confusing

      Did this swap myself and was a little confused. Found this site and it helped me out a bunch. Hope this clears the wiring issues up for yall.

        thanks that helps alot, btw what ecu did you end up running? we are going to be running a p13 from a 95 prelude along with an obd2 to obd1 conversion harness and eventually he will geta chipped ecu from phearable

            Distributor Wiring

            I've had quite a few requests for distributor wiring so I've taken the time to add this update. The only wiring I have is for the H22a equipped with an internal ignition coil.

            Sensor OBDI wiring (prelude dist) OBDII wiring (accord dist)
            TDC Orange/Blue Green
            White/Blue Red
            CKP Blue/Green Blue
            Blue/Yellow White
            CYP Orange Yellow
            White Black

              For the crank angle sensor. Look for the wire on the obd2 that has to plug up near the crank from the engine harness. Run the wire to the internal dizzy. I forgot what color wires but it should be what ever is left from finishing tkp, ckp, and cyp. If yall want things to be easier just buy the distributor jumper harness.
