Would anyone happen to know or can show what the wiring for the downstream o2 sensor is ? I think it's the following , but not certain -

O2 Sensor - O2 Connector Socket in engine bay

Black - Blue = Heater
Black - White with Green stripe = Heater
Blue - Brownish green color = Signal
White - White = Ground

 

excursion, looking at the diagrams, this is what I am seeing as far as what the vehicle side of the wiring is (doesn't list what the sensor side is as that can vary from manufacture to manufacturer): Please note that the items in the parenthesis are for bank 2 and those outside are either for Bank 1 only or apply to both banks.

Pin 1: Blue (Blue with yellow stripe): heater ground
Pin 2: White-Green (White-red): Heater power
Pin 3: White: lamda sensor ground
Pin 4: Brown: Signal wire

 

Exactly what I needed -- Thermo to the rescue

Thanks a million !

 

Wiring diagram. Color codes for o2 sensors. No plugs. Only lose wiring. Want to wire up bank 1.up ad down. Bank 2.up ad down. correctly. Your help be great full

 

Cris, not to question what you bought, but from our experience on the forums here, if you have O2 sensors with no pre-fabricated plugs on the end, you are going to most likely have tons of issues. Yes, they are cheaper than the others, but for some reason, they just don't work so well inside of our Jags. Can you make them work, you might get lucky. But, I think you are going to find that spending a few extra dollars is going to be well worth a lot of your time.
