Connector for oxygen sensor?

Where is the connector for the wires for the rear most sensor on a 2003 Prerunner?

Do I pull the plug/rubber bung down from the bottom of the truck to find it?

Or is it inside under the seat somewhere?

 

Anyone know the size and pitch of the 2 nuts for the sensor?

There is hardly anything left to them so I'll have to use a splitter or vice grips and get brutal with it.I've read on here its 12mm,but on mine a 8mm seems to start.

 

M8x1.25

 

Thank you. I have those in the shed.

 

You do realize that Wyoming09 described the thread size, not the nut size.

 

how can you have bolt heads on studs??

Thing is M8 x1.25 DIN bolts are 13MM across the Flats

JIS (Japanese Industrial Standard) Are 12MM across the flats

Thread size is M8x1.25

 

I understood.The size and pitch of the stud was what I was looking for.And the nut that goes on the stud takes a 13mm wrench.

Thank you guys.

 

OOPS, my error, I forgot those were studs.

 

Well…..that only took 4 hours…..


There was hardly anything left to the old nuts.Had to drag half the tools out of the shed including the torch. I wanted to see if I could get it without replacing the section of exhaust…..job done.

Connector is under passenger seat rail BTW…..had to pull the plastic rocker cover and lift the carpet.
