J125 Caravan connector 93

I have two problems with my caravan 93.
The first one that I have a j125 labeling connector that is disconnected and I do not find where it goes, I send them 2 photos to identify it and if someone knows how it is connected, I do the favor of supporting me.

The second case is that it does not turn on with the key.
The process to turn it on is the ignition key, I open the chest, intercept the cable that goes to the starter solenoid and the one to the battery positive, the starter engine is energized and the march begins, since the solenoid cable withdrawal of the battery is started.

I would appreciate the support they can give me to the present, taking into account that I do not know the name of parts or its location, when they give me a tip complement it with videos on YouTube.
Thank you
