Disconecting o2 sensor bank 1 conector
 

Does any1 have any tips on getting to the conector on a 97 non cali forward o2 sensor, i can just barely get a finger on it, and going thru the floor i cant see it

That is why it pays to have good dexterity in your fingers.

I think after the first time I left the harness free of being secured to the transmission and cable tied it where it was easy to cut and have the plug within easy reach from underneath.

On a Cali truck that forward O2 sensor is bolted to a bracket that can itself be unbolted thus making it easier to replace.
