Welcome. I have been fixing the 580f case for some time. It's time to replace the electrical system. 80% of cables have molten insulation and are torn off. Simple connections like lights, a starter can handle it. However, selenoid, valves and other sensors that do not know what their function are hard to do. Maybe someone has information or diagrams about these connections? Thank you, greetings
Welcome to HEF, Silut ! Your 580F is a European machine that I have never seen in the US. Not many of us can help you. Maybe Alrman will see this and help. The parts book will help you somewhat. There are a lot of drawings in it. Maybe you have already looked at it. If not use this and determine which machine you have. https://www.mycnhistore.com/us/en/casece/na/light-equipment/loader-backhoes/f/cn/NA_E_S_49_387_F If you can afford to purchase the service manual it would be money well spent. There are quite a few choices on eBay. All of them are in English.
