AE86 with 16V 4AGE wiring loom connectors identify

[Fukuen]

Hi all,
Recently purchased an AE86 with 16V 4AGE done by previous owner.
I'm starting to tidy up the car and find out there are a few unknown connectors in the engine bay which i'm hoping to identify.

To start with it's an AUDM 86 and the previous owner has removed the air-con and heater.

At the moment, my cluster does not have any reading on the Oil Temp? Oil Pressure.
I found the oil sender switch near the left side of the Oil filter with a blade, however, I couldn't find any connectors that would fit it.
The only connectors near that area are these.





Sorry that I can't insert the photo for some reason.

Can anyone shed some lights.

Thankx
