    I have a 93 cx , I put a b16a2 in it. I used the stock cx harness to wire it up and it is running fine except the o2 sensor is not hooked up and the check engine light is on. I've looked at all the pinouts for my p28 and everyone tells me the same thing ... org/blk-a6...grn/wht-d22...yel/blk-a25. I've done that and the car won't start, it makes a really bad noise. Does anyone have a clue???
    P.S.the v tech isn't working either(still beatin' v-sixiz')
    Thanks for any help,
    MeL :puke:

    you need to add wires for the O2 sensor.
    One wire from O2 heater pin of ECU to black on sensor.
    One wire from switched 12v to other black wire on sensor.
