After searching my mind is shot. My question is : I have A Maestro MS-OPS2 Occupancy Sensor switch. I have 1950's wiring. In the wall there are 2black wires and both are hot. There is a neutral bundle-3 white wires connected together which are not hot. I will ground the switch to the metal box in the wall.Where do the two blacks from the Lutron sensor go and the green insulation over a white wire go and the bare wire go. What connects to what? Thank you for your help.
