Default what do these electrical connectors connect too?

Hiya peeps,

So I've an FA20 engine that been used as part of an engine swap. I hope this doesn't offend people?

There are 3 connectors on the engine wiring loom that weren't connected to anything, what with just having the engine delivered from the scrappers.

Now I'm pretty sure the 5 pin wire goes into the airbox on a BRZ but aside from air temp does anyone have any idea what else it's sensing?

The other 2 connectors bolt on a bracket to the top of bank 1 chain cover, as marked by red oval in picture below.



Any idea what these 2 connect too?

Cheers in advance

Do you have a photo of the actual connectors? Also, you might have better luck in the FA forum section.

Here's a photo taken from the web with the connectors circled.



I may have had a light bulb moment and these are the pre and post cat lambda sensors.
