If I were you I could keep the 4 you have and wire up 4 more for your corners. The cool thing about the 6 dump setup is that you can lift sides. That's why we wire them like the way your truck is. If you wanted to add switches for your corners you could do that though. Derek or I could probably wire them for you and just leave a label on each wire, so you know where to connect it in your existing switches.
