2.3   Electrical System installation

           WARNING! Death or injury may occur from working on a charged electrical system.
           Disconnect the battery at the ground cable (if not already done.)
           Your factory horn or starter switch can be used to trigger the nitrous system.  The Switch is for arming
           the system. Use the diagrams below to help assist you with the installation.


           Note: consult the factory shop manual for proper wiring if it is not covered in the following
           diagrams.
           Some models provide +12v when the horn is activated. When using wiring diagram #2 the solenoid
           wire polarity will need to be reversed if the horn button provides +12v.











































            : SOLENOIDS HAVE TWO BLACK WIRES, IT DOES NOT HAVE POLARITY SO USE ANY WIRE!
                                              Factory Horn switch wire colors
           Hayabusa & GSXR1000 = Solid black
           ZX12R = Black with white tracer

                                             Factory starter switch wire colors
           Hayabusa & GSXR1000 = Yellow with Green tracer
           ZX12R = Blue with white tracer

           NOTE: On newer GSXR’s the headlight goes out when the starter button is pressed. You will be
     required to jumper some wires together to bypass this so the headlight will not go out while using the starter
     button as the activation switch. On the starter button harness, attach the orange to red wire, then the yellow
     to white wire. Check your wiring diagram before doing this to make sure it’s correct for your bike.
