oil send unit, found, question on other

ok well i pretty much figured out where the oil sending unit was,once i got the right part(fucking autostore) now when i goto install it i CANT for the life of me pull the damn electrical connection off....while trying to do so i gently(and i do mean gently) nudged another sensor going into the block.well it broke off the end of the sensor and left it connected to the electrical connection(god for bid that even happen on my oil send unit) and i have no clue what that sensor even is, i can try and get pics up but its the sensor on the right of the oil send that goes right into the block(if ure under your car looking up) please help because my damn haynes manual is stupid and neglects to have any damn clue about either of these 2 sensors

i believe it's an oil pressure sensor. there's 2 of them on the back of the block. one right in the center and one more towards the transmission.

ahhh so theres 2...interesting.i was just worried it was something important like a crank positision sensor or some other made up thing in my mind that would fuck my engine. =P
