I don’t know anything about the PCB you’re referring to. Odds are that it’s fine. If you’re really worried you can voltage divide with resistors.
As far as the SOCD cleaner goes, with the brook ps3/ps4 fight board, you have 2 choices for the SOCD cleaner. by shorting 2 points, you get the last input overrides the last you are looking for. L then R = R, R then L = L, U then D = D and D then U = U. no fancy wiring required
