    i am running an obd1 p28, and i've been having o2 sensor problems ever since the b16 swap.

    now i got a new o2 sensor and the car runs exactly the same when the sensor's unplugged and when it's plugged in. i don't want to go through my whole wiring harness, so i'm just gonna run 2 separate 4 gauge wires (is 4 gauge right?) from the o2 sensor directly into the ecu pin.

    so there are 2 black wires, i assume they're the ground wires.

    from the reference section there are 2 Primary O2 sensor inputs for obd1 p28, ecu pins D14 and A06.

    my question is this:

    are the 2 colored wires coming from the o2 sensor putting out the same signal? does it matter which o2 sensor wires goes to which ecu pin?

    whats the difference between D14 and A06 pins?

    thanks wiring gods. i'm an electrical idiot :worthy: :worthy:

    don't forget the o2 heater wire.
    p28 have only 1 o2 sensor.
    a6= o2 heater
    d14=o2 signal
