I need a wiring diagram for a P/MM setup, similar to this:

But I want a switch atleast for the MM to make it paraller/series.
If some guru would kindly help me by telling me what components I need (on top of those shown in the pic) and where to wire em all.
Also would like to know how to ground it all properly. Is it just a wire through every pot attached to bridge?
So in the end the setup would be somewhat the following:
P vol
P series/parallel(/off, if possible)
MM vol
MM series/parallel(/off, if possible)
tone
perhaps a killswitch. Am I correct if i say it's just an on/off switch near the jack?
