O2 sensor wire bundle nowhere to be found...!?

[MakoML]

Well I used to be a XJ Cherokee fan until I test drove a 92' Explorer to buy for the kid. What a nice ride, plan to get another 92-94 Explorer for myself and retire the XJ to offroad only use until it finally dies.

But, the 92' XLT 4WD I bought her has some issues that I am working through (only paid $1100 for it). Main issues right now is that the O2 sensor that is installed in the Y-Pipe at the area just before the Cat, the wires& plug from the sensor itsef are hanging under the Exploder not hooked up to anything, causing the Check engine light to come on after driving a few miles. I have been under this thing all day and for the life of me cannot find the wire bundle and plug to hook the O2 sensor into.

Can anyone tell me the general location of where I need to be looking? It appears from the exhaust setup that this Exploder has only one O2 sensor instead of 2 or 3. I am starting to wonder if someone changed the exhaust and got the wrong one and I might find O2 bundles in other areas than where it needs to be???????

That and the 4x4 is inop, but I can handle that one, and a bad shimmy/shake at 45-75 Mph that goes away when coasting tells me U-Joints are bad.

But this O2 sensor thing is most important right now so any help is appreciated.

Been a while since I replaced the one on my 92. That connector is about on top of the bellhousing on the passenger side. I remember dropping a string down on a washer, attaching it to the sensor connector, and then pulling it up to the engine connector. That string never got removed till I pulled the transmission years later. It is a bear to get at from the engine compartment with one hand. If I thought about it longer, I probably could have gotten to it from the wheel well by removing the rubber flap. Anyway, that is where it is.

Excellent! thanks much! Good idea with the string, will have to consider that.

Ya, i took off my front passenger side tire and it was pretty easy after that.

hey i just had the trans out of mine. it was a whole lot easier to see like that.
a lift in the garage really helps too. but yes it is on the passenger side above the bell housing.

Like the previous people said it is on the bellhousing. I have a 92 and there is only one o2 sensor for this year of explorer. after 1992 they switched to 2 o2 sensors.
