You should put it under the sink with a switch where it's easily accessible.

Run the romex to a 1900 box under the sink. Have it feed a double outlet and two switches. One switch can control each outlet. Plug the dishwasher and disposal into their outlets. This is to code where I am in Illinois.

I don’t care what anyone else says about the dishwasher junction box being to code it’s a hack and sloppy work.

Did you do the long hike from the observatory?

I was out there a few weeks ago, my pictures don’t look nearly as nice as yours.
