Hi, if you still need a schematic there is one in this thread:

For extending the wiring to the float switch I used some wiring of the same gauge and used a 2 wire connector that I got at Radio Shack for a couple of bucks. It also makes taking the float switch out for cleaning a breeze. I also used a manual on/off switch which I use for water changes as I am sump less.
Hope this helps
Dave
