Just some new info for an old thread. Hopefully some one can benefit from it. I recently had to install the newer style transducer on my '96 Intrepid and of course needed the different pigtail connector. I didn't want to spend the $50-ish for that, so I remembered I had kept one of the old oxygen sensors that I'd changed out on it and wondered if that connector would work. ITS A PERFECT FIT! Now, it has four wires when you only need three for the transducer, but no biggie, just cut that one off.
Wire colors are not the same, so pay attention to which wire goes where. My old oxygen sensor had two white wires, a grey one, and a black one. Looking at the back side of the connector where the wires come out, I matched up the "lower left" grey wire to the blue on the transducer wiring. Then the "upper left" white wire to the black for the transducer, and the "upper right" white wire to the purple on the transducer. Works like a charm.
