FIRST OFF THERE IS NO WAY FOR THIS TO WORK AS THE STOCK TYPE KILL SWITCH DID. BUT IF YOU JUST WANT A COSMETIC LOOKING BIKE, THE LEVER PURCH IS THE SAME. YOU WILL NEED TO MAKE A JUMPER WIRE FROM THE SOLID BLACK TO THE BLACK WITH WHITE STRIPE WIRE'S THAT USED TO GO TO THE ORIGINAL SWITCH....(IN OTHER WORDS) THE BLACK WITH WHITE STRIPE MUST HAVE 6V WITH THE KEY TURNED ON. AND NO VOLTAGE WITH THE KEY OFF. ALSO IF NOT ALLREADY JUMPERED (SOME ARE) YOU WILL NEED THE SOLID YELLOW WIRE TO THE WHITE WITH YELLOW STRIPE, OR TO THE CONNECTOR THAT HAS A YELLOW TUBE, OR HALF YELLOW INSOLATOR. BOTH OF THESE ARE AC FROM THE ALTERNATOR WHEN ITS RUNNING.
