I just got a new Bosch 10272 O2 sensor for my 2000 4.7L 4x4. I finally got the old one out and noticed the new ones electrical connector does not match or fit. the plug on the receptor end does not line up with the sensor's plug slide tabs. the spacing is wider on the slides on the old sensor than the new one. its the sensor b4 the cat. Any help would really be great! thanks for your imput.

 

that isnt the rite part #

here are the #'s ya need both bosch parts
pre: 13272
post:13280

 

i heard the bosch O2 sensors werent any good.i really need to invest in both new 02 sensors, but just dont have thetime to switch em out right now. any suggestions on abrand other then bosch? i got the bosch platinum plugs and if the sensors are anythinglike these are iam def. not getting them.

 

right you are sorry, i was going off memory but it is a 13272 p/n. sorry for the confusion. Bosch is all the auto part stores have. I also went to the Bosch website and they give me the same number???? oh so still confused

 

or go with borg warner, idk if these are universal tho, if so you would have to clip the ends and splice....

up: OS1026 or OS194
down: OS841

 

You might be replacing they wrong O2 sensor. I am assuming one is pre cat and one is post cat. Try to hook up the connector to the other O2 sensor's location.

 

yeah i checked that out too. but still no fit i dont get it??? ITS A FREAK TRUCK!!!! NOOOOO!

I know there are 4 there somewhere
