Default What are the 2 sensors on the rear of the VLOM?

Replacing a (gen V ls) vlom with a non AFM valley cover. The the old VLOM has 2 sensors/wires attached to the rear of the VLOM. When you order a non afm valley cover to delete afm they either come with 1 provision (drivers side) for a sensor/wire or zero. I think the sensor to the passenger side is PCV and the sensor to the driver side is an oil pressure sensor? None of the replacment covers has the passenger side provision. What do you do with these 2 sensors after deleting AFM?

The passenger side plug is for the AFM/DoD system, it controls that whole thing for the valley cover. The driver side sensor is the oil pressure sensor that you must keep. You'll just leave that plug back there with nothing in it for the AFM.
