On the top of my head is this sensor
From this description in Haynes I gather it's the fan run on sensor so not desperately important.
I thought it would be nice to fit one of those rubber boots over it, that some of the exposed spades like this sometimes have...Temperature sensor
From March 1986, a temperature sensor is
located between injectors 1 and 2. After
switching off the ignition, this switches on the
cooling fan when the temperature of the
cylinder head exceeds 110°C. A time relay is
incorporated in the circuit. This switches off
the function between ten and twelve minutes
after switching off the ignition.
but I've no idea how to refer to those rubbery bits to even start searching. Anyone got any ideas? Or even know what I'm talking about
