Sensor identification

[AfroRover]

Greetings from sunny South Africa.

My first post here, have found lots of usefull info before. Recently bought a 1980 RRC in running order but as can be expected there are lots of little issues that need attention. I am in the process of trying to replace the worst of the wiring (brittle, rubbed through etc) but find myself at wits end with the 3 sensors at the oil pump (they were all disconnected by the PO).

After trail and error I did figure out which is the oil pressure sensor but cannot find any reference in either Hayns or the RRC WSM for the other two. One is underneath the oil-pump facing down and the other faces up and is on the radiator side. It stands to reason that one of them should be the oil temp sensor (have tried connecting both to oil temp gauge, one does nothing and the other instantly goes to max). If anybody can help me ID these I would greatly appreciate it. With a beast as old as mine I think it is important to have some indication of how hot your oil is running at.
