More engine compartment and "what is this"?

[pcmcobra]

Ok guys,
here are some more pics. I have been reading my manuals, chiltons and haynes, have not picked up a factory service manual YET...
Anyway, any help in identifying these would be a big help. On the carb pic, that white/off white looking connector (circled in red)...I barely touched that thing and the clip broke, so I zip tied it for now. Have no clue what it is/does...
The others...I have looked on the wiring diagrams, but they did not help me much, one diagram said oil pressure sensor...
One way or the other, I will know what these are and what they do. Hope this post helps others as well. Thx
