O2 Sensor Wiring Diagram

Do any of you folks have a diagram or schematic of the passenger and drivers O2 sensor wire layout? The test pipes I purchased from Stillen include an O2 Sensor Intercept box that corrects the CEL. However, the schematic that Stillen provided is for a 2003 Nissan 350Z. Apparently, the color-coding varies and I have no idea what wires to splice.

This is what I see under my 2004 G35:

Passenger O2 Sensor:

BLUE/BLACK
PINK/BLACK
BLACK/YELLOW
RED/BLACK

Drivers O2 Sensor:

RED/BLACK
BLACK/YELLOW
BROWN/WHITE
RED/YELLOW

According to Stillen, I am supposed to cut/spice

Passenger O2 Sensor:

White/Red

Drivers O2 Sensor:

LG/Blue

They must be looking at a different car. Any suggestions are appreciated.

Thank you!
