It took a whole bunch of really smart engineers, with degrees and everything, to design our system to work as well as it does. Anything you can possibly do to the system to implement this "on-off switch" thingy will surely de-optomize it, and result in:
A) Lowered overall performance (if you're lucky)
- or -
B) Damaged engine components (most likely)
There are a lot of guys on this site making impressive and substantial horsepower and torque with modified SC's, but they've practically earned an engineering degree in research and development making the system work properly. They've also broken a lot of expensive hardware along the way, and spent more money than many people are willing to admit.
Trust that Ford hired the right guys to design the system, and don't try jury-rigging some B-movie gizmo to impress the Honda guys. Save your money for tried-and-true power adders that are outlined in excruciating detail many places on this site. Save yourself some money.
