If you want to organize your wirings, one way is to use electrical tape. That would give you a hard time removing the tapes if ever you need to make some adjustments and leave sticky tape marks on your wires. 

You could use this black spiral wrap to make your wirings clean and fast to remove. This wrap has a diameter of 10mm, but you could use it with thicker groups of wires. It is 10 meters long, but you can cut it depending on your needs.
