Re: switch/outlet combo
On the switch/outlet combo the one side with the brass screws should have a jumper between the outlet and the switch. You connect power to the brass screw and common the the other side of the outlet that way the outlet is always hot. The other side of the switch goes to the outlet for the disposal so it is controled by the switch. You should then have a wire from the hot side of the switch to the dishwasher outlet brass screw and a white wire from the common to the other side of the under counter outlets. The outlet under the counter should have the 2 silver screws jumper together the other side needs to have the jumper between the two brass screws removed.
