What are those parts?! 1974 1,8l car Options

[TRS63]

Hello,

I am slowly getting in the direction of putting things back on my 1974 1,8l and I have those parts that were either connected (I have pictures of them mounted, and can put them back but I want to know what they are!) or there but not connected to anything (so probably not needed but who knows !)
Here the pictures :

#1

connects to cylinder head temp sensor.
in mine it is in the loom and pops out near the cht.
yours might be hanging around seeming on its own because the loom is not in its casing any more? thats what i think. though its a white cable on mine. maybe yours got oversprayed by PO or something. the connector is def the cht one and i don't have any other connector like that over there going anywhere else. least i don't remember one and i can't see one other than the cht.

can't help with #2 unless i crawl under car.

keep up the good work.
