behind distributor near the oil pressure sender unit,you can barely reach it removing the distributor cap (may be a single or coupled unit (pressure sender/oil switch)

I think that pic is the oil pressure switch (two prong) for the fuel pump circuit and the oil pressure sender for the gauge (single prong)

The oil temperature sensor is above the oil filter on the side of the block. It looks like this:

there are different layout for this unit 84-85-86-87-88 switch (two prong) and pressure sender,it is a one unit in 89 like the first pic,your 91 uses the same switch as 89
see Ecklers

Sort of a trick question ?? There is a temp sender and pressure switch. Not a temp switch.

oil temperature sensor is over the oil filter housing,this is for oil temperature gauge.Behind the distributor there is the oil PRESSURE sender (for oil pressure gauge),and oil switch,this is a backup feature in case of a faulty fuel pump relay.
