where can i find a wiring diagram for a nos setup. also where can i purchase a activation button for the handelbar?

 

you can go to nitrousexpress.com and go to the installation guides, then click on the carb plate system, and there's a wiring diagram. You can buy the "handlebar switch", or also called a WOT switch or microswitch from Nitrous express, ebay, or most anywhere that deals in any nitrous brand. I can tell you how to wire it if you have a Nx system. You can buy a push-button at wal-mart or radio shack if you want to do it that way.
