4AGE 20V -> Exhaust temp sensor, do i need it?

Hello,

I was comparing the ecu and connectors with the picture (see below) that was on the internet. I noticed that i have 2 wires connected on an empty place on the scheme. I've marked the empty locations with a red circle.

What i've read on the internet so far it might be used for the exhaust gas temp gauge (the upper red circle) and the exhaust gas temp sensor (the other red circle). I assume they are for that purpose, but would the car run fine without that sensor? Does it have any consequences for the ECU if it won't get that signal?

Thanks.

EDIT: Part number is: 89425-19575

Temp sensor, no, O2 sensor, yes.

Should i connect a wire to the pin on the ecu so it has no resistance and thinks the temps is oke or should i solder a resistor to it?
I can imagine when the pin isnt connected it measures infinite resistance. Won't the ecu think then that the temp is too high?

Don't bother. There's tons of these swaps with no resistors, nada. Mine included, it's fine w/out it
