Plug under intake manifold rb25det s2

[StressedPoet654]

Wondering if anyone knows what this plug is for under the intake manifold right underneath the forwards most knock sensor. Its the same type of plug as the VCT solenoid but its only got 1 wire going to it. Currently redoing my starter loom and this seemed to not be connected or potentially I broke the wire by mistake. Hopefully someone can let me know if its needed at all. Facebook and quite a few different searches had no results.

Also where are these 2 small plugs supposed to go? They seem to be just grounds but they dont have a home to plug into. Car is factory auto but now manual if that helps so i do expect excess plugs and wires

The First one looks like an aftermarket Knock sensor, might explain why its cut? Almost certain it is this:

The other two plugs not too sure. are they just a single flat female (as if they would slide over a male spade terminal?)
One has standard looking conduit over it suggesting that this was an aftermarket addition as well maybe?

There are some temp sensors that are just a single wire and earth through the base of the sensor so it may have been for oil and coolant temp sensors?
