Need help to ID this SC sensor please
 

Picture one shows a sensor that is unplugged straight back, other sensor on the right is plugged in. I believe one of these is the idiot light for the oil pressure gauge.
Second pic is far right on the engine close to the bumper, again unplugged - what does this do?
I appreciate the help, the PO has changed so much I am still trying to figure things out.

Which year SC is this? The sensor on the right chain cover is the 50c temperature switch for the lambda unit.

Sorry -1983 SC that has been converted to carbs. As the lambda unit is unplugged I can assume that sensor is not needed?

Yea, you don't need any of that stuff for carbs. I should have guessed carbs since you can actually see the oil breather in your picture.

Temperature switches......
 

The first one on top of the engine near the breather hose is the 35°C/95°F SW and the other at the chain housing cover (right side) is 15°C/59°F SW. Both needed for CIS fuel injection system and disabled for carburator system.

Great. What sensor is the one plugged in towards the back with a red top on the first picture?

Oil pressure Idiot light.
