if your replacing it with a bosch the two black wires (stock) will go to the two white ones (bosch), no polarity so it dont matter which way you hook it up. The blue one (stock) will go to black (bosch) and the white wire (stock) will go to the gray wire (bosch)

I have a factory O2 sensor (BLU, WHT, BLK, BLK) and a truck from some dumb-a that cut the plug off the truck-side of the wiring harness... (BLK, BRN, WHT/RED, PNK/GRN).

i found your answer sir
The pink/green might be tan/green and the yellow/red might be white/red, my crap is probably just old and faded

Thank you for the pic, I appreciate your follow-up and I'm sure the next guy will too.
I've actually had it hooked up for a couple days now and I was able to get the info to hook it up right after searching here for a while.

wow, wierd, my Bosch was easy to install... it plugged right in
I tried one of the universal ones like that first, but it didn't want to work for me, so I just got a direct replacement

he was asking about the truck side of the plug (pink, brown, yellow, black). the instructions that come in the box, Bosch at least, refers to the colored wires on the O2 side of the plug (blue, white, black, black)
