What the heck is this stuff????

I can't find this on the wiring diagram. What is it?




This green wire is on the passenger side. There is what appears to be a sensor in the head down there. If it was on the drivers side I would call it a temp sensor.




Here is the green wire for the temp sensor on the drivers side.





Now these blue and black wires go to a plug on the passenger side of the carb. What are they???




Here is the plug.




Well, these are my questions of the week. I hope my pictures are good enough to see what I am talking about.
