The default module for both the switch and relay is slot 4, if this matches your configuration you can leave it unwired, but it doesn't hurt anything to wire in a constant Slot 4 to be sure.

You should wire in a constant for both the switch and relay channel that matches the channel you are using for each on the Digital Sidecar.

EDIT: From the image it looks like you are using controls instead of constants for the module and channel. While this will work if done properly, you probably aren't changing the module and channel very often so a constant is probably more appropriate. Right click on the control and select "Change to Constant"
