300Tdi locating coolant temp sensor?

I have a sensor in the middle of the top of the head that appears unused, but I dont see the coolant temp sensor location anywhere.

I have that same sensor, I think, towards the back of the head looks like maybe a two prong type connector? Nothing is plugged into mine either. I also have a 300 tdi Disco.

Found it after following the wire. They really hid the little bastard.

the sensor in the head is only for engines with EGR. This was on all Land Rovers in countries with emission regislation. No problem if it is not connected, just the EGr doesn't work the engine will even run better.

Is this sensor a thermal switch (ie: on/off) or suitable for hooking up a secondary temperature gauge. If the later, what is the sensor resistance range. Any suggestions on suitable gauges?

This it? ERR2081

That is certainly a sender and not a switch. I'm not sure that helps anyone unless you have a programmable gauge and want to take the time to calibrate it. Knowing the thread size would be useful in sourcing a known sender. The interwebs say it is M12x1.5

So it seems that sensor is useless unless connected to something programmable - eg an ECU or some kind of eg raspberry pi homebuilt engine monitoring system.
