307 XT, automatic, idle socket

Friends my vehicle 2004 model, gasoline-lpg, automatic XT 307. When I was cleaning the last butterfly, I caught my attention with an idle socket that was not attached anywhere when I removed the air filter box. Do you know what this socket I marked in the picture is for?

I have the same thing, but the socket on me looks very similar, but a little different. Whatever I need to consult so many people, let's do it, maybe the owner of the previous one has a mistake so that we can complete it. But every mechanic is saying the same thing: 'If the car is running, it is not a problem if it is not a problem, that cable is already free. It is there for a different model or different variations. Most of them are in the car, things etc. 'As a result, as they say, I don't have a bit problem, but there is a socket socket there, standing towards the back of the battery :)

Just like our friend @recepagdas says, this type of socket can be because of the version difference or the motor type.

I think I found the end of this socket under the wheel nqs 2019-05-20 12:07:43
