i thought it would be cool to buy a "vsc off" button (i got one from a 99 Camry) and put it in.... but the button only has continuity when it is pressed down then when u let the pressure off it loses continuity any one have any insight on how to make this switch work or know were i can get the wiring diagram from the Camry... or is it a loss cause and that is why i have not seen this done??
