• The ST763 temperature sensor is connected by the red WT or OT wire.
The unused black wire should be tied back to the harness. If this type
of temperature sensor is to be fitted at a point between two plastic
sections of fluid line or hose where it is unlikely to have an earth
contact with a metal part of the engine, add an earth connection
between the place where the sensor is to be fitted and an earthing
point.
