Help Identify part

[timon31]

Hi, so after the 120K service my 300ZX 1993 NA started to leak a little bit of oil so I raised it to look for the oil leak and found the Pinion and some spots near the transmission and oil filter to be leaking, but looking around the pinion area front to back I found out a "sensor" that has 2 black cables (one broken and the other about to brake and I have no idea that this is.

This both pics are taken front to back




And also a picture of my oil leaks =( wich any input here its appreciated, Leaks started after the 120K and Shaft Center Bearing Replacement in december, all fluid leves are fine, but the leake a little in my garage.

Sensor is the "power steering pressure sensor".
Oil filter leak might be from the oil pressure sensor above the filter.
Other oil leak between rear of engine and tran; most likey rear main seal.
Both oil leak "should" not be caused by a 120K service, since that is all front of engine work.

Thanks, Maybe de leaks have to do with the replacement of the center shaft support?

Another leak possibility is the valve covers which do leak down the back and present just like what you show...as do other areas as well though to be fair.
That was my leak, which I thought was rear main seal.
