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
