sup guys i was reading around trying to find out how to wire up the universal o2 to the oem plug but came up short and didnt get anything, so i finally figured it out and got it right so i decided to do a small write up so other people with the same problem can now have an answer. so its starts out like this:

step 1: remove the 6 bolts on the spark plug cover, disconect the o2 sensor plug

step 2: remove lower intercooler pipe to give u more play room so u can remove the o2 sensor

step 3: use the propper wrench to remove the oem o2, because the last thing u want to do is strip that thing!

step 4: once u got the oem o2 sensor pulled out wat ur gona want to do is measure it with the universal one
and cut the oem clip off. Cut it off long enough so u have a little playing room incase u mess up

step 5: now wat ur gona want to do is merge the oem o2 sensor clip with the bosch universal o2


Step 6: in able to combine the oem clip with the o2 ur gona have to merge the wires, this is how they are color matched, the 1 blue oem wire goes with the 1 black bosch wire, the 1 white oem wire goes with the 1 grey bosch wire, the 2 black oem wires go with the 2 white bosch wires (the black ones can go with either white wire) strip each wire and sodder it, then wrap it with electrical tape, here are some pics of the wiring: sorry for the cell pics lol

 

sticky!! im assuming its the same for the rear?

 

thanks for the detailed pics and explanation, i just returned my universal back to pepboys because the wires were different colors.
now I'm going back lol

what type of lead is used?
also i'd wrap them in heat shrink

 

Thanks for the writeup! My o2 sensor is still going strong but my buddies crapped out on him the other day so this caught my attention. No way in hell will I spend $250 when this can be done!

 

can someone confirm this is the correct way

 

i can confirm it. i replaced both of mine with ones off of a different vehicle that was totaled with just a few thousand miles.

 

thanks man

 

U guys are welcome =)

 

I can confirm this as well. Did mine almost a year ago just like this and it's still going strong! Very good write up!

 

Old post, I know, but I can confirm this as well. Car runs great!

 

A friend told me that a 2004 Mitsubishi Montero or a 2000 Montero Sport 3.8L oxygen sensor also fits. Does anybody know if this is true?

*The sensor being a 4 wire type also, I figure it might.

Or should I tell him to keep his crackpot ideas to himself.

 

yes its the same sensor

 

I confirm also but it you buy a socket for the O2 sensor and the ratchet, you can do it without going underneath the car. (Depending on your setup Bigger manifold,...etc) I have the Buschur Ported and coated mani.

 

product number please?

 

Can someone please measure the stock one and let me know the proper length to make the new one?

I did this yesterday, but did not cut it to the same length, so the check engine light is still on. It runs great, but the code is still there even after I had it cleared.
