After putting my carburetor back on and getting everything hooked up correctly I noticed I have a leftover connector. It is green and for the life of me I can't remember if it was connected to anything before I took the carb off. I made a point to label all of the connectors (or so I thought) when taking the carb off so I am really clueless if this is supposed to be connected or not. I saw another 12a fb the other day that had one just like this that was not connected so I am just curious if someone knows what it is for and if its normal that it is hanging freely unconnected to anything.

It is on the passenger side of the engine bay near the carburetor where all of the other connectors are hooked up. Sort of underneath the passenger side of the airbox. I can't find any other connectors (green or otherwise) for it to connect to.

 

I have a 85 GS and mine is not hooked up to anything either.

 

Choke Return Solenoid Valve - - which solenoid valve was eliminated from most Nikkis sometime in 1980
If you had a green-dot solenoid on the carb, it would go there. Part of the early 49-state Fed emissions system.
Connector B-19 on the 1980 (Except California spec) wiring diagram.

 

I tried reading through the wiring diagram and didn't get very far. Glad someone knows exactly what it's for

 

I tried reading the wiring diagram and couldn't find it either! Always glad for people with tons of random knowledge lol.
