I'm trying to replace my O2 sensor (before the cat) for '99 2.0L, and want one with the OEM connector (least amount of work preferred). But the onces that Autozone and Kragen's that say is compatible (Bosch) has a round connector, the one that's installed in the car right now has a square connector. I did find one that had a square connector but it's suppose to be for the 98, will this work? or shall I just go to the dealer and get an OEM sensor?
Thanks,
Ted
 
Just get the correct connector of the correct O2 sensor (replace upper for upper, and lower for lower) and you should be good to go. The Ford OEM is actually a Bosch.
