There is a set of wires that come from the ON/OFF switch on the left hand side of the handle bar.... follow the wires to your hood... then there will be a BLACK wire and a BLACK WIRE WITH A WHITE STRIPE on it... just connect one of the "kill switch's"wire's on one of the two and the other wire on the other wire of the bike. NB Remember that the wires should not be cut off from the bikes ON/OFF sitch they should just be joined in there.... LOL hope you understand what I am trying to say here ill post a drawing for you in a few min.
