-The ignition module is an Ultima Single-Fire ​version, feeding separate trigger signals to the dual coils to fire the front & rear spark plugs separately.

Using the VOES connection ​ (which helps with idle & cruising spark timing by providing more advance) is recommended, but implementing ​a tachometer is optional.+The ignition module is an Ultima ​version and fits in the nosecone where previously only the cam sensor plate was mounted. In this diagram the __Ultima ​Single-Fire ​Configuration__ is used, feeding separate trigger signals to the dual coils to fire the front & rear spark plugs separately ​(the Ultima BLUE wire fires the front coil & the Ultima PINK wire fires the rear coil).

 +If you choose to use a __dual-fire configuration ​of the Ultima ​ignition__it will also work when you pair it to the appropriate dual-fire coil. In that case, you will only use the Ultima PINK wire to fire the selected dual-fire coil. (The Ultima BLUE wire will not be used at all with a dual-fire version.) 
 + 
 +Using the VOES connection ​with either configuration ​(which helps with idle & cruising spark timing by providing more advance) is recommended ​by connecting the Ultima VIOLET wire to the VOES unit. 
 + 
 +Implementing ​a tachometer is optional. If used, the Ultima GREEN wire will connect to the tachometer signal input wire. The tach will also need a ground connection on the bike and key-operated power for the tach light.
  
 There are only six wire colors to minimize wire purchase: **Black - White - Red - Blue - Yellow - Green.** There are enough colors so that no connecting point should have the same color twice in order to make it easier to know which device is connected to/from another device. There are only six wire colors to minimize wire purchase: **Black - White - Red - Blue - Yellow - Green.** There are enough colors so that no connecting point should have the same color twice in order to make it easier to know which device is connected to/from another device.
