I have no electrical experience outside of a 6th grade class project making a simple circuit with a switch. There are some bad schematics online that are literally just wrong. This one worked http://www.instructables.com/id/Radi...our-Rheostats/ Just wire the on/off switch in the neutral line between the power source and fan. Not that you needed my help, but I figured I'd lend it if it can help someone.
