1993 2L 2.4 diesel super custom.temp and fan sensors missing

hi
just bought a hi-ace super custom problem is, the fan is running all the time, temperature gauge does not work, thier are 3 wires ripped and sensors holes bunked up this is located near where the thermostat sits and coolant filler cap is,i want to know the numbers on the sensors so i can buy correct sensors, ive worked out that one wire is for the fan(ground it and it will turn on-off fan),1 wire is for the temperature gauge(ground it and temp shoots straight up and the other i believe might be the ect wire (which sends signal to the ecu), problem is thiers only place for 2 sensors, just wanting to know the numbers on the senosrs or a close up photo, so i can get correct senors,many thanks in advance
