I tried looking at the fuse box in slot 7 and the fuse looks fine and I have tried putting a new fuse in and have had the same results.
Did you completely cut ANY wires in the process of installing the switch (Not just wires that are applicable to lighting)? Remove the newly installed wiring, ensure all factory wiring is intact, and see if everything goes back to normal. If so, you did something funky with the installation. If not, you have a bit of a larger issue.
