Zetec Blacktop HO2S Plug Wiring
tims31 - 27/11/15 at 08:12 PM

Today I de-pinned all the engine loom plugs for my Blacktop Zetec so I could route them through a grommet into the engine bay, plus I shortened a load of them now I know how long they need to be. The trouble is now I have checked all the wiring and that’s ok but I have a conflicting diagrams in regards to how the HO2S plug is wired pin to pin.

What I have is one that shows:

Pin 1: Green/Blue (Pin22 from C2513 plug to switched live)
Pin 2: Black/yellow (Pin 93 on ECU
Pin 3: Brown (Common Earth)
Pin 4: White (Pin 60 on ECU)

And the other one has

Pin 1: Black/yellow
Pin 2: Green/Yellow
Pin 3: White
Pin 4: Brown

I know where the wires go to and what they do, I just need to get the correct wires into the correct pin location for the sensor which is wired:

Pin 1: White
Pin 2: White
Pin 3: Grey
Pin 4: Black

Could anyone please have a look at what they are running and let me know the correct way to wire the plug again

I will double check in the morning for you, remind me if I foget.

The two white wires are the heater and can be wired either way around.

Hey Warren,

Standard NTK/NGK Zirconnia sensors and some Bosch

Black = Signal
Grey = Sensor Ground
White = Heater + Supply
White = Heater Ground

Whites can be wired either way round

Thanks,

Found this online which I think is for a Focus 2.0ltr zetec but pretty sure they will be the same wiring...
