The Nitrous Express wide-open-throttle switch only is the WOT sensor element sold without the relay, bracket, or hardware. It provides the throttle-position switching function for nitrous activation but requires the purchaser to supply the relay and mounting hardware. Use it when you need the WOT switch itself for custom wiring or to replace a worn switch while reusing existing mounting components.
