Where do I plug these cords in?

I have a b350m gaming pro mobo, but I don't know where to put the case cords. My specs are

Deepcool Tesseract Case Ryzen 3 MSI B350M Gaming Pro Mobo 8GB of Crucial DDR4 Ram and a VS550 powersupply.

I can't find anything on how to plug in the case cords into the mobo. Thanks
