The Bosch universal one comes with this cool little kit whereby you "make" a connector, screw these little threaded pieces onto the end of the wires, the thread and crimp on as they go down, then teh two halves connect together. I did this on mine a few years ago... when I replaced my exhaust, some !@#$ PO has welded the o2 sensor into place.

Now... I have never felt like the a/f ratio was good after that, always been suspect of that sensor and connection. If I could, I'd go back and just get the one weth the OE connector. My paranoia has not been worth the $50 saved.
