Drainage systems

Hi All
one of my cline has recently changed his double drain sink with a single drain sink.
I now need to redo all the plumbing to allow for single drain usage.
I am having a hard time trying to find what is the proper way to install the disposal and dishwasher to a single drain,
and at the same time what is the proper layout of the PVC piping.


we will highly appreciate your feed back.
Thanks in advance.

You think you're having trouble figuring out how to do it, I can't even see what you are trying to hook up!

How about a picture?

I would think the disposal, of coarse mounted to the sink, will have a inlet for the dishwasher at the top side. Now is your drain in the wall or through the floor? P trap to this I would think.
