OBD2 S52 Oil temp and pressure sensors

[eternal24k]

Of course I did not have everything perfectly figured out before the motor went in, and now I am trying to figure out how to add an oil temp sensor. I am pretty sure I am going to go with the Rally Road option, but not sure what part number for the oil temp sensor. What did everyone do for the second sensor location and part number?

I should mention I have OBD2 S52 with E30 M3 cluster. I am thinking these two might be the sensors i need:

You are looking for the m3 sensor right? Or are you missing the oil pressure sensor for the low oil pressure light? That sensor you linked should be the oil pressure switch. It only warns you if the oil pressure drops below the allotted pressure.

You should look on realoem.com under archive e30 m3.
