Post an update when you get a chance!

So there is a cable clip pushed into the plate and I don't think I can get it loose with out cutting it... Spent 30 min trying to get it out..*arg*.. I guess it is impossible to know if I can do without something holding the nearby cable right there but I might have to go that route.

The struggle continues...

I could not dislodge the connector from the plate on my 92 either.
Finally used the long screwdriver method.

Today I had some more time to work on this. I was able to remove the clip from the plate. It helped to temporarily remove some of the plastic around the cable near by. Eventually I got the o2 sensor connector loose. Soon it's time to remove the sensor after some lubrication. And then we will see if I can get things back together...IMG_20200916_203621.jpg

I have replaced the last sensor and Iam putting things together. What does the picture tell about the left and right side? The left one is new, the middle is left side and the right is from the right side. There is a noticeable difference in color... IMG_20200917_195043.jpg

I'll wait to hear what other more experienced folks have to say about the color, but meanwhile I'll note that the removed left and right sensors are not the same part (look at the shape). Maybe someone previously replaced the left (driver) sensor but gave up on replacing the right (passenger) one due to the difficulty involved!

[Wigert]

That is a good observation! Maybe someone gave up on the right side as you pointed out.

If someone else will be doing this the torque specs might be useful to know (at least valid for 1990):

Two oilpan bolts 10 NM
Two front crossmember rear brace to front side member bolts 58 NM
Two front crossmember rear brace to drivetrain and front suspension frame bolts 56 NM
One engine mount frame nut 54 NM

I cut the wires at the sensor and installed a new Weatherpak connector. Plugged in the new sensor and looped the wires up and out of the way and was done.

Later, when i installed my OBX headers, I didn't have to find a harness extension.

Now that is a good idea!

Are the two white wires interchangeable? Otherwise how did you determine how to wire the connector properly?
