NewV

I want to do simple NB simulation with a permanent install of my WB02. This is a PLX WB so I need to place a 20 Ohm resistor across the NB Heater power and Heater ground. I can then use the controller output to the NB O2 signal input. Sounds simple enough but I want it to look clean. I've ordered a new NB pigtail but not sure which of the 4 wires does what. I have a PCM diagram but don't want to tear apart my front end to get to the PCM to see what color the wires are.

Does anyone know what the 4 NB wires are by color or location on the connector? Basically its 2 each power and ground for heater and signal but which two?

On the PCM side of the connector the wires are grey/white, red or pink/black, yellow or brown, brown or purple/white. Hard to see down there. On the NB side of the connector I have 2 black, 1 white, 1 blue. I'm assuming the 2 black are grounds.

This is an 2005 LS6 CTS-V, thanks for any help. BTW I've seen the LC-1 hookups but none of the wires are described by color.
