electrical. just a usual temp sender.
sensor will be near the thermostat in the housing if i remember correctly.
they are not particularly accurate and only give a vague idea of " cold, hot or somewhere in between", but better than nothing
you may be able to just unscrew sensor from 4K and screw into 3T thermostat housing.
there may be more than one temp sender, but maybe not.. if there is no efi or thermofans
