O2 sensor plug

How in the world do you plug the O2 sensor in into a '93 ZJ? I'm doing my exhaust in a few days and was underneath today after an oil change measuring and what not. Anyway, I bought a new sensor (mines got 86k...figured "why not?") So I trace the wire from the sensor in the pipe up until it disappears above the tranny. Don;t tell me I gotta drop the tranny just to plug in a sensor?!?! looks like there's a panel up there. Think you can remove the center console and plug in from above?

Remove the heat shield above the exhaust pipe and slide it back. Then get a coat hanger (I actually used thicker wire) and bend it into a U shape at the end to hold the top of the plug. remove the old sensor and plug the new one in BEFORE threading it into the exhaust pipe.

Removing the heat WOULD work, just gonna be a squeeze. Thanks, man. Also, very good call on plugging in BEFORE threading in new. Nice!

yeah, I have replaced my O2 sensor twice, last time was about 3 days ago. In my jeep I couldn't reach the bottom of the plug with the heat shield there but I may have bigger arms/hands or my exhaust is in a slightly differn't place.

only twice, first time was 2-3 years ago. The check engine light came on for the O2 sensor. The second time was 3 days ago because I have been getting worse mileage than I should be (I should be at 17-20 and am at 15). I figured it is the O2 sensor causing the worse milage because my driving habits have not changed and the bosch sensors supposedly only last a year or 2 in our jeeps. I will find out in a few days, I replaced it with a mopar one.

the sensor you have will still fit even with the bigger diameter. It is what I used the first time I replaced my O2 sensor.

The wire runs up along the tranny about 6 inches to the connector. After the connector I think it runs up into the engine compartment somewhere.
