How to know o2 sensor is wired in correctly?

[Barker]

Hello all I’m currently trying to add a primary o2 sensor to my setup. ‘97 ITR kswap

My problem is my swap loom (Sparkks racing) has 2 heatsheilded wires but no labels so I have no idea which is primary or secondary. They also have no plugs, so I don’t know which wires are for which function. Currently waiting to hear back from Sparkks racing to see if they can clear this up but if anyone else knows that would be great.

Once it’s wired in, how can I tell in kmanager that the car sensor is working? I’m not quite ready to run the engine yet, will I be able to tell it’s working with just the ignition on or does the engine physically have to be running?

I gave it my best guess but not seeing any signs of it being recognised by the ecu
Both sensor voltages say 4.08V
In error codes both sensors say ‘supported’ but status ‘not complete’


Any help much appreciated
Thanks

Okay Sparkks got back to me and I think I can distinguish the primary and secondary wires now, and also wire up the sensor correctly (let me know if this looks off)

So now I just need to know what to look for in kmanager so I know it is recognising the sensor, and if the engine needs to be running

Thanks

It needs to be running to be able to read what is happening.

It needs to be running to be able to read what is happening.

So there would be no difference between it reading the atmosphere and not being wired in correctly ?
