Had the same problem with mounting the old O2 sensor in the header
collector.  I used a 3-wire sensor off an Escort at the j-yard (cause it was
easiest to get to).  It had two wires the same color and the other
different, either blk/blk/wht or wht/wht/blk. The single color is the sensor
feed and the other two are +12V and ground (interchangable).
