coolant sensor wire
 

i just put my motor back in and was putting the radiator back on and when i went to put the coolant reservoir back on and i noticed i forgot to put the coolant sensor wire on, but when i went to find the plug i was not able to find it, does anybody know specifically where this wire come from, i couldn't find it on the main harness.

also on the passenger side there is a hose that i don't remember pulling it loose, it say gas/fuel on it, but the fuel line is already hooked up and it didn’t smell like gas so idk, it goes down right around where the main harness hooks in, also it is in a connector with another hose that has a green cap, i don't know for sure but i think it might be an air line, i might need to check the ac compressor for loose lines, anyone know for sure?
