Step 10Add a knob for looks, and enjoy!

Cut off part of the potentiometer shaft (I used a dremel), and throw a knob of some kind on there. You dont even have to, it just makes it look nice.

Simple! But thats because you did an awesome job on the instructions. GREAT JOB. I wish only a few of the adults on the Corvette Site I belong to could explain things as clearly and completely as you have done. I really like the idea one guy had of adding a motion detector to trigger the Flush lights - now how about one for put the g---damned seat up!! and Wash your hands. The only problem I see is naming your yacht after you have made a fortune selling these things restaurants and other public bathrooms.
