Passenger side engine bay sensor identification

[White1972k5]

1972 Chevrolet blazer K5 four-wheel-drive

gauge bezel includes battery temperature and oil pressure.

all gauges seem to function fine.

I have seen other post referencing blue wire for oil pressure sensor but I don’t seem to have that wire in my engine bay at all. Please see pictures below.

Thank you for the help.

Coolant temp sensor. Probably not needed because you have one on the other head or intake manifold.
I would leave it be.

Ok. I was a little confused because it has one on the other side that seems to work fine.

Did they come with two?
