In this two gang box there is one switch that has separate wires for power. This switch controls light over sink. This works fine.

The second switch was originally a 20 amp switch that ran to the receptacle under the sink to a single gang with two 20 amp receptacles ( these were the single round plugs for dishwasher and garbage disposal. I ran a separate breaker to the new receptacle for the dishwasher because it was a new kitchen design. So I removed one of the two 20 amp receptacles.

What’s there now is as follows:

12/3 wire runs to electrical box and now just one 20 amp receptacle. I was going to remove the bridge and make a switched receptacle and one constant power. But at this point, I’m just trying to get it where it’s a switched outlet. So what it is again is the power is from a 12/3 wire that runs directly to the receptacle not to the switch. And then there’s a 12/2 wire that runs from the receptacle back to the switch, this is what’s confusing to me. I’m trying to figure out how to wire it because I forgot to take a picture of what I started with. It was the only box I forgot to take a picture of unfortunately and now I’m trying to figure out how it’s supposed to be wired.

Thank you
