Hello from Bilbao and urgent consultation!

Good, I introduce myself to the forum, I don't know very well how it works and if I have wrong I apologize beforehand. I am looking for the electrical scheme of the Tiguan solar roof, I have recently acquired the roof and I have no idea how to connect it to work. If someone can give me a hand, I would appreciate it greatly! I have looked for workshop manuals, but I don't get any electricity. Attached image of the connector that has me crazy!

Thanks and greetings !!
