I'm converting my old TopWisdom TL-403 to a Ruida RDC4554G controller. The motherboard switch over has gone fine. Except I have one wire from the TopWisdom board that I don't have a clue where it goes. It is the U origin Limit labelled IN-8. Also I'm wondering if there is a diagram or something out there that would help me with the wiring switch over for the power supply. Would greatly appreciate any help.

Small typo correction it should be RDC6445G

The U channel is not used so it should not need a limit switch. I am on vaca so I don't have my schematics here but if you search for the controller # you should find it.
