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 ​version ​of the Ultima ignition__, it will work with the appropriate dual-fire coil and you will only use the Ultima PINK wire to fire the dual-fire coil. (The Ultima BLUE wire will not be used at all.)+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 ​version ​(which helps with idle & cruising spark timing by providing more advance) is recommended by connecting the Ultima VIOLET wire to the VOES unit.+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 ​and if used the Ultima GREEN wire will connect to the tachometer signal input wire. The tach will also need a ground ​wire (Ultima BLACK wire) and maybe key-operated power for the tach light.+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.
