Working With Diagnostic Data Cable & Software

When I translated to English the parameter files for PCHUD I had a problem with one of the temperature parameters.
It translated as either Engine temp. or Exhaust temp.
The readings were too low to be the exhaust temp. so went with Engine temp.
The problem is that i can't figure out what sensor is giving the data for this.

At one point i thought it might just be a mirror reading of the coolant temp. But the readings seem too different for this to be the case.

The only temperature sensors/ switches i can find are the fan switch attached to the left radiator and 2 on the thermostat housing.

According to the wiring diagram the sensor with the 2 pin connector goes to the ECU and gives us the data for the coolant temp parameter.

The other single wire sensor goes directly to the speedo, supplying the data for the " LCD heat bars"

Any ideas please
