The blue plastic connector for the rear drivers side (USA) oxygen sensor was torn off my car by a speed bump. This is also known as Bank 2 Sensor 2. I'm trying to match up the wires but I can't seem to interpret the wiring diagram... any help would be very much appreciated!

Thanks in advance!

02 sensor has 4-wires

Black
Grey
White
White

Harness from engine/ECU has 4-wires

Black/Yellow
Pink/brown
Orange/blue
Red/Black

I just need to know which wires go to which color. This is for a 2003 350Z Coupe w/manual transmission

Got it! Thanks to "Eazzzzzzy" for the PMs and time he took to go under his car and check the wiring for me. I hooked it up as per his directions, cleared the code and 75 miles later still no codes

Thank you for all the help!

I no longer have my Z and didn't save the PM's. Your best bet is to find another similar year 350Z owner and have them check for you.

I have the 03 FSM, and I copied a page for you, but the uploading/attachment feature here is not working right now, so I couldn't upload the image... sorry.

O2 sensor
B = 4
P/L = 3
B/OR = 1
R/B = 2

Connector pinout (latch is on top):
{}
( 3 1 )
( 4 2 )

I hope that helps....

I posted the images from the FSM in this thread (just in case the above explanation doesn't clear things up):
