temp gauge sender
Discussion
Oops! Sorry, but if I follow those instructions I find these,

The front item being the thermotime switch, the rear being the coolant temp sensor.
The gauge temp sender is usually on the front of the inlet manifold, here:

Connected by Lucar connector to the single wire.
For future reference, and just as an example, if you are looking for a similar remote item, locate the component on your workshop manual main circuit diagram, identify the wire colour, the gauge sender is item No 47 and wire colour GU on my cct diagram for SD1, yours should be similar.

and then try to match that colour wire at the expected component physical location - Seemples.
