I have a double sink in kitchen same size. Looking to install garbage disposal for my first time. Do I install it on the right (white pipe) or left side (black pipe)?

I assume the right side (white piping) since my dishwasher is connected to it and drainage is on the left side.

Is this correct?

Thank you

You will probably find the right side easier to plumb as there is just more space. Disposals have sort of a weird offset discharge pipe that isn't just a drop in replacement for the existing extension pipe. As you noted the dishwasher piping already runs to the right as well, and that is generally connected to the disposal.
