signal goes through bridge rectifier, So there is no polarity on this connector.
But this device is designed to augment existing mosfet ie signal is 12v or 24v, I do not know if it would work on a 5v digital signal, I though it did...
also check your 5v really is 5v, as mega2560 Voltage regulators die really easily.
Mosfet on voltage is 2.5v, (for the mosfet on the version of this board I have) so a low 5v on the mega would explane it
