Cut off the 3 wires the switch comes with: 2 go to your stock yellow starter switch, one is for a light (I put a small LED in the right control housing so I knew when the system was 'unlocked')
White: oil pressure sensor output so it knows when the bike running. Some need a tach signal, Crank or Cam sensor output is fine.
Grey/White: Just ground it, or use it as an extra safety by hooking up to the kill switch (unit won't operate unless it sees ground here)
Brown white: Same as above but unit will operate only if it does NOT see ground here, as if an alarm was armed
Blue/white: Brake light wire (or clutch switch wire) unit will crank the engine when the button in unlocked AND this circuit is closed
Green/white: no connection
Yellow/White: no connection
Brown: No connection. It will activate with the RFID, turn off while cranking and turn back on once started
Yellow: The activate the stock starter
solonoid (Not the starter itself)
Blue: The stock ignition circuit that does NOT control the fuel pump, it also turn off while cranking)
White: The stock ignition circuit that activates the fuel pump (it's from the kill switch)
You can make all of these connections at the ECM with the pin-out from the manual (Buellmods.com or Buelltooth.com)
