sensor ?

[kully 560]

I have a 1983 280zx turbo motor and there is a sensor on the passenger side left of the oil filter and between the oil filter and the oil dip stick.  now on the other side of the oil filter is the oil pressure sensor but I do not know what this one is . it reads normal open with a ohm meter and has 2 electrical connections on it and screws into the block. I am thinking it might be temperature and if so if I can use it for controlling my electric cooling fan. thanks

think its a knock sensor

yes Dave I am not sure what this is also,  if I can not use it I would like to plug it up if I can find what the thread size is ?

It screws into the block, or the head?
