cannot find where 91 Bronco II 02 sensor plugs in to harness

[tresvatos]

I got under my BII last night to do an alignment and noticed my 02 Sensor near the Cat is dangling.. The sensor is installed in the exhaust and the wire and plug are still good, I just CANNOT find where in the world it plugs to. I have searched forums for a day now , and get everything from near the starter, to near the relay Box, to on top of the Xmission. I have been under the BII and been covered with grease while my family is enjoying Easter looking for this plug. Does anyone here have any clues or insightas to where the single 02 sensor by the Cat plugs to.?! thanks for the quick help as my fuel economy and engine response is lacking because of this. Happy Easter as well!

If you Grab the harness near the distributor and follow it down you should be able to find the oxygen sensor plug.

The info you gave me was exactly right! I found the wire tucked under the larger wiring harness leading from the dis.cap. Thanks so much, I have ben under my BII all day looking!
