Ok, thanks for clearing up the function and name of the switch. I could be dead wrong, but I don't think your understanding of how that switch works electrically is exactly correct.  The center terminal is connected to the end terminal on the same side in the opposite direction of the toggle. Another way of saying that is that if you looked at the switch from the side, and the toggle were in the up position, then the center terminal would be electrically connected to the bottom terminal on THAT side. I don't thing that the right and left side of the switch are electrically connected. But I could be dead wrong on that, because I don't understand why the blue wire and white/ black wire are connected to the other side of the switch because as it is wired they do nothing.

Let's do some detective work before we try to finish the schematic. Do me a favor and check the continuity, with the ohm function of a voltmeter, the rear terminals of the Level switch.

This conversation and confusion has my curiosity up. The post started with you wanting help with the schematics. Would you mind stating why? Is it the system did not work as you thought it should? You suspect some wiring changes have been made? Just plain curiosity on your part? Do you have an unconnected wire that you are trying to figure out where it goes? Sorry to be so nosey, but I am trying to figure out what we are trying to fix.

I originally wanted the schematics to understand what wires went where after I noticed the Leveling mode switch had two red wires connected to the same terminal.  One red wire connects to the diode bundle and the other feeds back to the fuse panel as an ignition on power source.  
You are correct, the left and right are not connected, but if both center terminals have power, both top or bottom terminals will too. 
That brings me to the blue wire and black/white wire question about if they are connected correctly and if the red wire  from the fuse panel, currently piggybacked with the other red wire, should be moved and connected to the empty center terminal?
Now that I'm out of the mindset this is automatic, I shouldn't be as confused going forward.
