Im thinking about adding an On/Off switch to my meth system and failsafe kit. I will be driving around on a base map until the car is tuned and who knows, I may someday get a WOT tune without meth. Does anybody foresee any issues with a switch ran to these systems?

Aside from the obvious! It has occurred to me that if I am driving on the map that utilizes these systems and I have them turned off it could be catastrophic.

 

nobody has an opinion or experience with this?
