MMU2-DIP no connect on mk3s

Good afternoon, I'm trying to get your board to connect with a mk3s and it's impossible, I let the mk3s fully charge and restart the mmu2s-dip board and it still doesn't connect, do you have to change any position wire? Thank you very much.

Start by reviewing the MMU2-DIP and MK3S connection setup, including the reported full charge and board restart steps. Confirm whether the board connects and determine whether a wire position or other setup detail is required, then document the reproducible cause and resolution.
