Ok on my 2000 I dont have a rear o2 connector and there hasnt been a sensor there, just wires. I need someone to go out and look for me which wire connects to what.

It will be to a bosch o2 sensor, the colors are:
white - heater
white - heater
black - signal
gray - ground

All the wiring diagrams I can find dont have my wire colors which are:
brown
yellow
red/white
pink/white

Thanks!

hey, that's how mine are, unfortunately, my tib is 170 miles away

Hmmm, did I post these when I did my sensor relocation DIY? I can't remember man.

I can tell you when I get home I think.

I searched around but didnt see that thread. Ill check. Thanks

Redz, if you (or anyone else) could check that would be great. I found the DIY and it doesnt list the colors. Thanks

My rear o2 sensor is currently IN the car, BUT I've got my wideband out of the car, and it's wired PnP, so I can give you pics and all if you'd like.

Between that and a wiring schematic from HMAService, you should be good.

I do need some good pics of the LC1 all wired in to be PnP.

If anyone can check the rear wires for the O2 I still need that. HMAService had the wrong colors.

the problem is that the wire colors differ year to year. i have like 3 different O2 pig tails and all of them have diffent colors.

hopefully this might will help...

For future reference if anyone searches for this the correct wiring is:

pink/white goes to white (heater)
red/white goes to white (heater)
yellow goes to black (signal)
brown goes to gray (ground)

any1 know the wiring of yellow/green, red/white, gray, and black?

wiring from the ecu side to bare wires from oxygen sensor
